I have two gpus (7900xt and 9070xt) both were detected during the setup phase but afterwards only the 7900xt is used.

=== Step 1: checking your PC ===
  Your AMD GPUs:
    GPU 0: AMD Radeon RX 7900 series (gfx1100), 20 GB VRAM - can be used
    GPU 1: AMD Radeon RX 9070 series / AI PRO R9700 (gfx1201), 16 GB VRAM - can be used
  [ok] GPU: AMD Radeon RX 7900 series (gfx1100), 20.0 GB VRAM, gfx1100 (AMD: docs/AMD_HIP.md)
  [ok] RAM: 62 GB
  [ok] CPU: AMD Ryzen 7 7800X3D 8-Core Processor (AVX-512)

```

Is this an expected behavior?
