Rmt_set_pin for TX will enable the output driver by default, so you could immediately disable it or rewrite the tx pin setup

Active drive is probably only a problem with multiple parasite power devices doing simultaneous conversions.

But you should enable open drain mode in init either way.

Re: What is the purpose of two OTA partition?

Factory will not be updated, but it is also not required. But it is insurance to be able to factory reset to a (hopefully) known stable firmware even after many ota updates.
