ASRock B450M-HDV R4.0: Modifying ACPI FACP table to enable ACPI_S0_LOW_POWER_IDLE

Hello, I have an ASRock B450M HDV R4.0 paired with a Ryzen 7 2700, and I enabled Modern Standby/“S0I3” by enabling S0I3 and some other options using AMIBCP (by making Enabled the default for 'em), then I had to dump the ACPI tables, edit the FACP table to change “Low Power S0 Idle”/ACPI_S0_LOW_POWER_IDLE from “0” to “1”, enable test signing, and drop my modified facp.aml in system32 as “acpitabl.dat”, and modern standby works now, but I can’t figure out how to save my modified facp.aml to the UEFI image itself so that I don’t need acpitabl.dat anymore, is there a way I can go about doing this?
