Stuck with creating SSDT-AWAC

https://dortania.github.io/Getting-Started-With-ACPI/Universal/awac-methods/manual.html

Currently I am following this guide to make SSDT manually. However I could not find any ACPI000E in DSDT.dsl I dumped on the system.

My motherboard is Asus H310M-E R2.0.

Meanwhile there is a RTC device in the DSDT.

I wonder what should I do in this case.

Extra question, is XHCI-unsupported required for H310 even if I only use the onboard USB? Can I install this kext post-installation because I don't want to mess with all the details to compile specific kext for the system.
