On my all LHR rig, I can lock the core on each GPU by passing the following parameters:

--cclock @1350,@1200,@1200,@1400,@1200,@1350,@1200

It has the following GPUs:

0 3070Ti
1 3080Ti
2 3080Ti
3 3060Ti
4 3080
5 3070Ti
6 3080Ti

However, I also have a rig with a mix of 1000, 2000 and 3000 cards as follows:

0 1070Ti
1 3060
2 1070Ti
3 2080Ti
4 3080Ti

I want to lock the core on GPU 4 @1200.  How do I do that since some of the other GPUs don't support core lock?
