Windows 10: How do I easily get these SSD partitions I want with least SSD wear

For new laptop with only Windows 10 Pro 64 v1803 & some utilities installed:

I HAVE: a 1 TB SSD (NVMe M.2). Win 10 "Disk Management" says SSD has:
952 GB total Capacity [gigantic] in my C: Windows partition
52 GB used Capacity [small] in my C: Windows partition

I WANT: the 1 TB SSD (NVMe M.2) existing C: Windows partition to change to:
266 GB total Capacity [optimum] for my C: Windows partition (52 GB used)
686 GB total Capacity [optimum] for a D: Data partition

PROBLEM IS: Win 10 "Disk Management" only allows a Minimum of
505 GB total Capacity [overlarge] for my C: Windows partition (52 GB used)
according to size info it gives me when I right-click & select Shrink.

Above is my situation now. Can you answer 3) brief questions below?:

1) Am I correct the answer to getting the partitions I want is to use better defragmenting and partitioning tool(s) than Disk Management? OR, is there some other approach I must take (and if so, what?)?

IF such better tool(s) are the answer, NOTE 1a) through 1c) below:

1a) I'd like the easiest documented way to get the above partitions I want, since I'm UNknowledgeable on defragmenting and partitioning.

1b) I'm hoping for easy defrag/partitioning tool(s) for a SSD with priority on defragmentatiion to a set size so reduce wear on the SSD (i.e. defragment SSD only enough so existing 52 GB fits in set size of 266 GB,
then easily shrink the C: partition size to 266 GB and set me up a D: partition with size of 686 GB).

1c) I'd prefer free tool(s), but am willing to buy tool(s) for much better ease of use (and defragmentation only to a set size as per above paragraph).

2) Should the tool(s) generate a CD/FlashDrive I boot from, so I can defrag the C: partition (because cannot defrag live Windows OS C:?)?

3) ***What specific defragmenting and partitioning tool(s) do you suggest I use to produce the partitions in the I WANT: paragraph above?

Thanks for any advice and answers you can provide.

Unable to assign drive letter to SSD partition

I have recently installed a new SSD drive into my PC. It has bootable Windows 7 with two "healthy" primary partitions 500MB and 111GB. However it is impossible to assign drive letter to any of these partitions. Right-clicking on each partition gives grayed
menu options except "Delete Volume". How to assign drive letters to these partitions?

SMART data is OK:

Partition an SSD good or bad?

When you make partition, you don't actually limit SSD controller from spreading data beyond seemingly strict boundary.

When you partition HDD, those partitions are actually physically restricted on disk platters. In case of SSD, you see it as a partition, OS sees it as a partition, but SSD controller only sees entire SSD as a single block of cells that it can use and shuffle around to manage wear leveling. It needs to view it this way for efficient garbage collection and TRIMming. Otherwise, SSD would grind same partition over and over and wear it out too quickly compared to other bigger partitions. Same goes for files. On HDD, program could possibly overwrite same physical sectors over and over thousands of times. On SSD, when you overwrite files, they never write to same location. Which is the reason why data recovery from SSD's is incredibly hard. Data is never where it should be based on logic we know from HDD's.

I didnt realize an SSD does that, good to know.
