Module powering voltage on differnet module id

I’m designing a carrier board and confused on the powering voltage level on VDD_IN pins. In schematic p3768 version there are two methods given using different module id. But is it possible that i won’t make it compatible with 5V and HV voltage both at different ids. rather then just simply connect to 5v voltage line both cases and remove this MV/HV power mux circuit

Orin nano module is 5V only. Orin NX module is 5V~20V. So you can use 5V only for both nano and NX.

So should i just leave the Module ID pin either floating or pull up.

The pin is for mux. Just leave it unconnected if you have a fixed power supply and no mux used.

thank you
