Powering Omnibus F4 V5 using PDB 5v AND have the Voltage meter

Hi all.
I’m about to buy the Omnibus F4 Version 5 as it fits my needs.
For now I have a Matek PDB (powering vtx and camera) with a SPRacing F3 controller + Racerstar LiteS Esc.
Is it possible to power from 5v filtered PDB and having a Vbatt voltage?
I know is possible to power from battery, but just afraid to get some interference on vtx/camera/osd.

if you power from the 5v filtered your only see 5v as voltage

Your need the full battery voltage from vbat
