Bitlocker leaves partitions it can't understand and system partitions (like the EFI ones) alone in my experience.

Dual boot users may have trouble accessing their Windows files if they don't configure Bitlocker to allow direct password unlock (I believe Windows 11 uses the TPM, possibly with a TPM PIN for interactive unlocking, which Linux can't use to access the drive). This isn't too difficult to work around, but it's an extra step.

I mean for instance. I dual-boot Linux and W11 atm. For some reason my Windows 11 needs to be formatted back because of the virus or etc or SSD replacement with fresh installation of Windows11 and of course bitlocker will be activated automatically after WIndows have been reinstalled it back from the scratch. Will this affect my other ext4 or Btrfs OS partition? or do I need to back up of my Linux important files on that partition before W11 mess up my Linux?

I don't see why it would affect anything but Windows' NTFS partitions. Unless you still use MBR boot, all you'd need to do after a Windows reinstall would be to re-order the boot entries in your UEFI settings. Bitlocker operates on partitions, not full disks.

You should probably still back up your important files, of course, just in case your drive randomly dies...
