Can't change memory clock for secodary GPU in F35/36

I use Fedora 36 with Nvidia driver and cuda v510.062 with 2x 3060Ti GPUs which are recognized, and working well.
I can modify power limit for both OK, I can modify Core clock for both with no problem via nvidia-smi
nvidia-smi -i 1 -pl 150 (for second GPU and works well)
and
nvidia-smi -lgc 1200 (for both GPUs and works well)
I see nvidia-smi -lmc 7600 (is not supported)
so I tried with nvidia-settings

nvidia-settings --verbose=all -c :0 -a [gpu:1]/GPUGraphicsClockOffsetAllPerformanceLevels=-100

WARNING: Failed to match any targets for target specification ‘gpu:2’, specified in assignment ‘[gpu:2]/GPUMemoryTransferRateOffset[3]=2200’

it works for gpu:0

nvidia-settings --verbose=all -a '[gpu:0]/GPUMemoryTransferRateOffset[3]=2200'

Unhandled integer attribute GPUMemoryTransferRateOffset (410) of GPU (0) (set to 2200)
Attribute ‘GPUMemoryTransferRateOffset’ (s5:0[gpu:0]) assigned value 2200.

I tried different variations of nvidia-settings command, but no luck
Any clues?
Thanks, D

Probably did not work because you said you have 2 GPUs. Those are [gpu:0 and gpu:1] so gpu:2 does not exist.

No I put right gpu index
nvidia-settings -c :0 -a [gpu:1]/GPUMemoryTransferRateOffsetAllPerformanceLevels=2200

libEGL warning: DRI3: Screen seems not DRI3 capable
libEGL warning: DRI2: failed to authenticate

whereas for GPU 0 I get this response:
nvidia-settings -c :0 -a [gpu:0]/GPUMemoryTransferRateOffsetAllPerformanceLevels=2200

libEGL warning: DRI3: Screen seems not DRI3 capable
libEGL warning: DRI2: failed to authenticate

Attribute ‘GPUMemoryTransferRateOffsetAllPerformanceLevels’ (jdm:0[gpu:0]) assigned value 2200.

I tried also on different hardware and same issue, but If I do Ubuntu installation it works, same hardware, same settings
