Hello! I am having this exact same issue. It takes about 3 minutes to boot into windows if booting with AMD graphics. If i simply restart it doesn't happen, but if i turn off the pc completely and boot it back after it takes about 3 minutes to reach Windows 11 Home.
The only workaround i've found so far is to enable to mux-switch and bypass the AMD graphics altogether. In this case it boots in 5 seconds. However, a fix from AMD is very much necessary since the laptop gets too energy hungry with discrete graphics only, which is part of a reason why a person buys a laptop, so it is on battery power.
Everyone with this issue please do also send a report, perhaps via the Bug Report Tool in the software?
AMD, please do look into this matter. (Also the driver install software causes Windows to crash sometimes)
