Please use Software & Updates to switch to the “-open” driver version and set kernel parameter nvidia.NVreg_OpenRmEnableUnsupportedGpus=1

how to set the kernel parameter ?
I just do :
add a confi file,and the file content is :‘nvidia.NVreg_OpenRmEnableUnsupportedGpus=1’
then excute:
update-initramfs -u

i get the error notice:
libkmod: ERROR …/libkmod/libkmod-config.c:712 kmod_config_parse: /etc/modprobe.d/nvidia.conf line 1: ignoring bad line starting with ‘nvidia.NVreg_OpenRmEnableUnsupportedGpus=1’

If you put it into a modeprobe conf file, the syntax is
options nvidia NVreg_OpenRmEnableUnsupportedGpus=1

thank you reply,
i put the parameta to :nvidia-graphics-drivers-kms.conf,
options nvidia-drm modeset=1
options nvidia NVreg_OpenRmEnableUnsupportedGpus=1

then reboot os,

then nvidia-smi , no device were found

and then, re nvidia-bug-report.sh, I notice the log :

Sorry, I didn’t notice you initially used the runfile installer which had to be uninstalled first, so that one is still active. Please switch to nouveau in Software&Updates, then run the runfile installer again with --uninstall option, then switch back to the -open driver in Software&Updates.
