Hi 10x Bios reset no keyboard

I need help.
Somehow my bios got mesed up, now i can not boot to windows anymore.
When i power up the tablet it goes straight to bios but i can not do anything as my keyboard does not work, i also tried keyboard via USB-C and also does not work.
I opened the tablet but i don’t find any battery for bios or reset pinouts.
Did anyone had same problem ?

Sorry for my bad english.

Try to disconnect main battery for 10-15 minutes, if this doesn’t help - you need to flash bios with programmer.

I tried the battery thing, and it didnt work.
I thought there was maybe some secret key combination or something. When i power tablet on the light on keyboard turn up for second and then goes away.
