OpenCore: Am I able to skip the IRQ SSDT, if I don't have an OS on the target computer? (Haswell) Could I install it after I install Mountain Lion?

Target Computer: HP EliteBook 840 G1 (Laptop)

• Intel i5-4300u
• Intel HD 4400
• HP S700 Pro SSD (Brand new/Nothing installed)
• 1x8 GB 1347Mhz

​

Current Computer:

• AMD R7 5800x
• RTX 2060
• Crap-ton of SSD's and 1 HDD
• 32 GB 3600Mhz

​

I know what the IRQ SSDT does, but is there an option for a preset like all of the other SSDT (Haswell), if I do need it?
