I had a GTX 1080 TI card, I bought a new, efficient RTX 3090, the card works great in Benchmarks. 
I installed new drivers.
Lightroom Classic 13.5. 
Driver 

Problem: the program does not use the card. It makes no difference whether:
1. Auto is enabled
2. Manual
3. Card support is disabled.

I checked the card on 2 drivers:
1. 560.81-desktop-win10-win11-64bit-international-nsd-dch-whql
2. 560.94-desktop-win10-win11-64bit-international-dch-whql
The effect is the same.

How can I solve the problem with exporting photos.

    During the screenshots, I exported photos from RAW to JPG. On the internet I found graphs that show GPU usage during RAW export to JPG. In my case it doesn't matter what I set.

    LC only uses CPU. to exports.

    Why do you sate that it is not in use. These sceenshots of usage are nice, but without context they are of no value. What were you doing in LrC when you looked at the GPU use? Were you busy in the Develop Module. Or were you in the Library Module? And does that use cover when LrC needed to use the GPU? 

     

    Library Module, will not be bending the GPU

    Develop Module may heavily use the GPU when callede for.

    Perhaps watch the GPU graphs while attempting a AI Denoise, or an Enhance.
