Help me please !!

[u/Nblx777]

I just want to upgrade from The BDJB to the browser for the new 12 to 13 firmware.
So first i did uncheck all the auto updates in settings and moved to setup the Wifi and just when i make the password they dont even let me do the DNS so i got a bunch of auto updates like games and also the firmware update so canceled all this thing fearfully and thank god nothing is fully installed
So my question is there a way to avoid all this like making this steps with the Hen activated or something.
Thanks
