[Request] Chinese BSLAY DS16 laptop bios hidden settings unlock

Good day, gentlemen!

I got an interesting laptop with two screens from a Chinese manufacturer with a processor Xeon w-10885m on board. It is also possible to connect an external graphics card via an external x8 dock, which is absolutely delightful. The model is called BSLAY DS16 and it seems to me that it is absolutely identical to Creelander DS16 and Nikear DS16. Now about its problems, the memory runs in CR 2T, SST and TurboBoost are disabled in the base. Of course, there are no customization options in the BIOS on this topic. Armed with the manual from the forum, I made a bios dump with afuwin program, opened it with AMIBCP 5.02 program and it shows that like all partitions should be visible, but no, they are not. I changed the ones I need to USER. When trying to flash via afuwin I got error 43 and actually never managed to flash from the system. Okay, I opened the laptop, armed myself with a ch341a programmer, made a bios dump with the help of NeoProgrammer and again edited it in AMIBCP and flashed it back, the partitions did not appear.

Question one:
Is it possible to somehow make it possible to flash from the system, since disassembling the laptop every time is a hassle?

Question two:
What did I do wrong?

Question three:
I will be grateful for help in modifying the bios. I think I need all overclocking settings for memory and processor (especially frequency, timings and CR), as well as unlocking Above 4g and Re-BAR settings in case of connecting an external video card, as in fact it will work as in native pci-e.

Here is BIOS (backup - original dump, mod1 - my modded file):
