Issue using 2 GPUs in Windows 11

Well, yesterday I bought a riser for GPU (those ones used for mining), I connected it to the PCI-E x1 slot and I gave it power by it's pci connector (6 pin), I plugged everything right and I installed NVIDIA drivers for GT 210, well, my main gpu is an RX 550

I saw somewhere that W11 could handle 2 GPUs at the same time, one only for rendering and the other one for video output only, in this case I plugged my two vga monitors to the GT 210 and in settings > Graphics doesn't allow me to use the RX 550 for rendering, unless I plug my DVI-D to VGA adapter to the RX 550, but I move the window from the RX 550 monitor to the GT 210 plugged monitor, seems that windows changes the rendering GPU and i'm so tired of trying without something positive, any idea?
