can USB be used to create a virtual com port?

OK I found why and it is normal (at least with the current implementation).
As Serial is no more mapped to SerialLP1 then the default pins defined in the variant_NUCLEO_L4R5.h (PIN_SERIAL_RX/PIN_SERIAL_TX) are not used as they are defined for the "Serial" instance.
So the correct way is to use setRX/TX.

I will check if I can use those defined pins when Serial is mapped to USB.

I've made a PR to fix this. Now when USB sepersed Serial, pins defined are used.

No, the USB functionality on a controller cannot be used to create a virtual com port (VCP). This type of functionality is typically only available on controllers that have an onboard ST-Link interface.FM Whatsapp

In that case, I just achieved the impossible!

And how do you think VCP works on ST-Link??
