Each OS is on it's own drive ? If not, they should be.

Disable the sata data cable to your macOS drive when you are updating Windows. If it's an NVMe drive and you can't easily remove it then hopefully you've set up OpenCore properly for a dual boot scenario.

Yes, each one in a NVMe that I can remove... with some effort

Could I just install again after the update, or I need to disable TPM every time I want to open MacOs? How can I know if it's set up properly for this scenario? (MacOs 11.1 Sidecar Working :lol: - Windows 10 fully updated)

Only Secure Boot needs to be disabled for macOS to boot.

I have Win11 and MacOs 12.2.1 each on its own physical NVMe m.2 SSD.
TPM is enabled in the BIOS of the motherboard.
Installation was rather smooth and I had no issues.
It's been a while now, but I'm pretty sure I did the MacOs install first.
Once that was working fine (OpenCore), I removed the MacOS SSD and installed Win11 on the other SSD.
Once that worked too, I added the MacOs SSD back in and pointed the motherboard to boot from that SSD (the one where OpenCore is on).

Cheers!
