Consider a dedicated SSD for each OS. You should have a couple M2 slots in the laptop. What you can do is remove (or disable) the Windows SSD, install Linux on the second drive, and then add back the windows drive. Select the drive at startup you want to be in on boot and default the drive you want to spend most of your time in. I did that on my XPS and it was trouble free. Linux can mount your NTFS just fine, without having to consider it from a boot/grub perspective.

Looks like you got space for 2 drive.

That's a terrific idea. It might address the other problem that I'd have little space for Linux apps. Thanks!
