Most CH341 come with a soic8 clamp, but all of these are quite cheap quality, so they might even be dead on arrival and the clamp won’t be of best quality to put it mildly. There are several guides / threads regarding use of a CH341 here in the forum.
Have a look into this thread, especially #5 regarding knocking off these SMD parts!
Yes, asus provides not a complete firmware image
Left complete firmware from linked thread, right Asus update
Asus has some duplicate EFI volumes- the ones between 289EFB98-9F4C-47F5-9AC4-35A4D847B0A9 and 61C0F511-A691-4F54-974F-B9A42172CE53- and an update to Intel ME region in DE90FFA8-B985-4575-AB8D-ADE52C362CA3
In case overwriting with stock you’d need anyway a valid dump to find out which of the 2 EFI volume tree was the right one and it would be a very bad idea, too, to take just a dump from another machine- might be correct tree, or might not.
Always make a valid backup (at least 2 a 100% identical dumps with a valid structure in UEFIToolNE) of every chip you want to flash!
