there are two ways to handle multiple payloads in coreboot:
1) have a single primary payload, which provides the mechanism to execute secondary payloads. Grub and SeaBIOS can do this; Heads and Tianocore cannot
2) have two primary payloads, and use the normal/fallback mechanism to select between them using nvramtool
Either way you'd need to read/modify/write your existing coreboot image, and in many cases simply rebuilding is easier.
For the example you gave, you'd want to use option #2 for Heads+Tianocore, since launching one of those from the other is not (currently) doable

Hi,
is it possible to run two Payloads on Coreboot at the same Time, like Heads and TianoCore?
Payloads can only be installed by building a new Image and Software-Flashing it, correct?
