I doubt, that an update of the Realtek LAN BIOS module will solve you problem.
It will only be loaded and used, when you are going to boot your machine via LAN using the Wake-On-LAN feature.

My current System:
MB: ASRock X570 Pro4, CPU: AMD Ryzen 5 3600, System Drive: 500 GB Samsung 980 Pro, Graphics: Sapphire Radeon RX570, OS: Win10 x64 Pro

It depends on your system and its BIOS.
Some informations about it would be fine.

I generally do not recommend to modify the BIOS of a Mobile system. The chance to get a bricked mainboard is much higher than with a Desktop system.
If you want to update the Realtek EFI LAN module nevertheless, you may try to let the UBU tool the work (although it has not been designed for Mobile system BIOS modifications).
Alternatively you can use the AMI Aptio IV UEFI MMTool manually. >Here< is a guide.
