22h2 win10 update with grub and wierd boot situation

Question

Hi. I have 3 partitions.

1. for booting with grub (heavily moddified, much work, cant replicate)
2. for win 10 + boot manager
3. for win 11 + boot manager
   (dont have 1 boot manager for both systems, not sure how I did this, but I did)
   Primary using win 10 21h2 and Im afraid about 22h2 update for checking/repairing my boot manager situation. I need to keep it untouched.
   Can you tell me, if this update touching/looking/repairing boot manager?
   I try clone hdd for backup, but my grub on cloned drive stop working after cloning (Im not expert i quess) so I need answere, if update is save for my system with this situation.
