I disabled it with the uf2 provided and I now I can inyect payload using usb.
I have tried diferent hekate versions, reinx, atmosphere payloads and all of them work flawlessly. I inyected sxos payload.bin and it inyects correctly and shows the sxos screen but it stops and doesn't show the nintendo logo, the screen backlight it's on but the screen is black. It is the same payload.bin that is on the sd and works when the chip inyects it, but I don't know why inyecting it using tegrarcm via USB doesn't start sxos.
It seems that the chip it's interfereing in some way with usb inyection.
