In fact iPXE _is_ launched from ROM but hands over control to EFI BIOS during its course of execution. The comment in the upstream sources [1] says that's done to support the PXE base code protocol, iPXE supports it natively only in Legacy BIOS. Please find more details in upstream's commit message [2] and in bug 1789319 [3] + [4] at Ubuntu which ended up in activating this behaviour in the ROMs. I opted to mirror what the Ubuntu guys did, and apparently also the people at RHEL/Fedora [4].
