your Motherboard Specs will tell your IGPU specs. So depends on which Motherboard you purchase or have.
As an example only, here is a Asus TUF GAMING B650-E Wifi Motherboard IGPU Specs: https://www.asus.com/us/motherboards-components/motherboards/tuf-gaming/tuf-gaming-b650-e-wifi/techs...
Another example from MSI Motherboard: https://us.msi.com/Motherboard/PRO-X670-P-WIFI/Specification
So it seems from the above Motherboard specs it supports HDMI 2.1 and DP 1.4
