Egpu nvidia card not seen by nvidia-smi

Debian Bookworkworm box (AI/ML workload) with Nvidia 4090 installed on mobo, egpu with nvidia 3060 installed and verified active with boltctl. Both cards display in lspci

0000:01:00.0 VGA compatible controller: NVIDIA Corporation AD102 [GeForce RTX 4090] (rev a1)
0000:3f:00.0 VGA compatible controller: NVIDIA Corporation GA106 [GeForce RTX 3060 Lite Hash Rate] (rev a1)

NVIDIA-SMI 535.183.01 Driver Version: 535.183.01 CUDA Version: 12.2
nvidia-smi only displays the 4090 and nothing for the 3060

both cards were visible/working once upon a time with a different distro (Kali)

How can I get the 3060 back in the mix to give some relief to my 4090?

TIA
