SELinux is preventing /usr/bin/boinc_client from 'open' accesses on the chr_file nvidiactl.

*****  Plugin device (91.4 confidence) suggests  *****************************

If you want to allow boinc_client to have open access on the nvidiactl chr_file
Then you need to change the label on nvidiactl to a type of a similar device.
Do
# semanage fcontext -a -t SIMILAR_TYPE 'nvidiactl'
# restorecon -v 'nvidiactl'

*****  Plugin catchall (9.59 confidence) suggests  ***************************

If you believe that boinc_client should be allowed open access on the nvidiactl chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep boinc_client /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
