Windows 10: How to prevent windows from starting unmounted drive?

I have a dualboot desktop computer with 2 SDDs and one HDD, one of the SDDs is for Windows 10, the other one for Debian Linux.The HDD is used solely for Linux and all partitions are formatted for ext4. But Windows briefly starts this HDD at least once per hour.Is there a way to prevent Windows from doing that?
