So for me it is now working:
Disable Secure Boot in Windows 11 ARM
In Windows, hold down the SHIFT key while selecting Restart.
Go to troubleshooting advanced options: UEFI Firmware Settings.
Then in the BIOS turn off the secure boot option.
Then in a cmd with admin rights type the following
bcdedit.exe /set nointegritychecks on
Then switch it on again:
bcdedit.exe /set nointegritychecks off
After this:
You have to disable driver signature verification.
