Does your Development board like the Ebyte, EoRa Pi route the needed signal to a non RTC_GPIO capable of external 0, wake up?

There is a solution; use a 74HC04N, six pack of inverter/buffers; use a pair of inverters for a HIGH input and and a HIGH out or if you need the inverted polarity use a single inverter. Simply route from the non-RTC_GPIO wake up signal to the first inverter input. Output of first inverter connect to the input of second inverter. Output of second inverter is routed to RTC_GPIO that is externally wake up capable! --credit goes to Microsoft's Copilot for the fix.

Or just use a piece of wire to connect the signal (also) to the pin you need it connected to.
Sure, using a buffer between the pins may be a little bit more safe-ish by potentially protecting the original signal (only!) from the second input pin being accidentally switched to output, but this is very marginally useful at best.
