I see the following in the setup instructions:

• NVIDIA GPU (We use Titan X (Pascal) with compute = 6.1, but we support compute_50/52/60/61 devices, should you have devices with higher compute capability, please revise this)

As it look at this, what is needed is not immediately apparent.  How do I revise for Compute Capability 8.6?

You need to check if your Graphic card support CUDA 5.0 or bigger.

As a RTX 3090, it supports CUDA5+, but it also has higher Compute Capability.  How can I set Compute Capability to 8.6?
