3080 ti driver RmInitAdapter failed!

my 3080 ti doesn’t work. I found the error is RmInitAdapter failed!

I found “nvidia: module verification failed: signature and/or required key missing” in bug repot. I am not sure what is this error.

I attached my nvidia-bug-report.log please check.

looks like error is from here,
