	If you boot from the iGPU (onboard) can you switch to the RTX3050 once windows loads?

	Is the RTX3050 installed inside your system or is it an eGPU (in it's own enclosure outside of the case)? I just noticed you said "external GPU". If it is external then this is normal operation. The UEFI lacks driver support for external GPUs, this would be highly impractical with the amount of space it would take up on the BIOS ROM. As soon as the OS loads and detects the external GPU things will work as normal. If the system won't boot at all without a display connected to the onboard output then you can try hooking up a second display cable to your monitor, most support more than one input. This is the price we pay for external GPUs, it can require some messing around to get things working. If it is an internal GPU (I suspect this is the case given you said low profile), then try different display outputs from the card. Some GPUs will have a preferred output and won't output a display until windows if it's not used. If that still doesn't get things working then check page 63 (67 in the PDF) of your software/BIOS setup guide for the UEFI settings to do with your primary display output.
