Code Block language sudo mount -uw /
This command doesn't seem to be working under Big Sur:
Code Block language mount_apfs: volume could not be mounted: Permission denied mount: / failed with 66
What should I do now?

Any further thoughts?
For example i would like to edit /System/Library/LaunchDaemons/tftp.plist file and add -l so i can log tftp to syslog. How you can do it ?

Thanks for the explanation.Therefore, I usually use my custom display profile to enable HiDPI support at 2560x1080, which requires access to /System/Library/Displays/Contents/Resources/Overrides/.
I tested this and can confirm it works, no need to disable SIP, change the boot security or mount the system files as read-write.Does the equivalent path in /Library work for this? If not, you should definitely file a bug about that. Please post your bug number, just for the record.

Code Block language sudo cp -R /System/Library/Displays /Library/
Code Block language sudo cp ~/Downloads/DisplayProductID-413a.plist /Library/Displays/Contents/Resources/Overrides/DisplayVendorID-10ac/DisplayProductID-413a
This works 4 me.
