33 is a problem. Pins on portB, the pins with numbers greater then 32, are inputs only. Well you can use them as normal ports but the coding is for using the pins as RTC pins not GPIO pins. Most likely I lost you by now, which means you cannot use portB for outputs. portB GPIO pins DO NOT have internal pullups and the input impedance is more in line to match the requirements of the A:D converter.

For relay module with an ESP32, I use the ones that use otpoisolation.
