Windows 10: Do I need to decrypt my data drives, D:\ or E:\ before re-installation Windows?

Hi, Now I am running Windows 10 Pro with BitLocker enabled on C:\, D:\ and E:\. D:\ and E:\ are my data drives and want to keep the data can access after re-installation. As I know I can either decrypt or no need decrypt System drive, C:\ because the encryption key will be erased when I delete the system partition in the re-installation step. But I'm not sure I must decrypt the data drives, D:\ and E:\ before re-installation the Windows or not?

A partition drive is e and not d in windows 10

Hi guys, when I installed windows 10 I did it using a USB. I went from windows 7 to windows 10. With Windows 7 I had made a partition, so I had OS (C and (Data (D. When I installed Windows 10 (using the USB), what used to be Data (D, became (Data (E,
as the usb became Drive (D. So what I have now, after removing the usb is: OS (C and (Data (E. And whenever I connect and external drive, such as a usb or a backup external hard drive, it becomes Drive (D. My question is if this is a problem, to have
OS (C and (Data (E, instead of Data being D:? Is it important for Data to be D and not E, because when I start my computer, I don't always have connected a Drive D? Should I always have something connected to the computer so it becomes Drive D? Should
I re-install Windows 10 and make sure that Data is D:? Is this an issue for having (Data (E and not as (Data (D? I'm saying this because it's not following a right sequence and C and E are partitions, which were part of a same drive once, and it's not
following a sequence now. My computer has had some issues and I'm wondering if this could be the cause.

Thanks!

Both of the Directly "advisors'" responses thus far fail to point out (in addition to misspelling "Disk" Management) that if the flash drive has been assigned the drive letter "E" it won't be an available choice when you try to change the
letter on the drive. You will need to first remove the "D" designation on the flash drive, then assign "D" to the partition.
