[BIOS Menu Unlock Request] Motile 14 Performance M-142

Hello, I saw the experts here have had success with the BIOS menus for the M141 Motile 14 laptop from Walmart, and was hoping for help with the M142 upgraded version. It looks like the original BIOS can be found here: www(dot)motilecustomerservice.com/m142.html, and I have attached a dump of the BIOS currently on the laptop following the steps for the FLASHROM tool. I would like to be able to use XMP RAM profiles or manually set RAM speeds, as well as tweak other advanced features that are currently hidden. I haven’t had luck finding any guides that explain what I need to do to edit the included BIOS file, but I am very new to all of this and my Google-fu brought me here rather than to the steps I need to be successful on my own. I ask for the wisdom of the unlocking masters and enlightenment for myself in how to do this on upgraded BIOS versions.

The file was 16MB and too big for the attachment feature in the forum: drive.google.com/file/d/1z4ExUtNJ_EiJotIxSj3FQrccvmPP1WSf/view?usp=sharing
