are there alternative ways to enter UART programming mode?

I managed to destroy GPIO0 pin on my board. I have a backup one, but I feel sad about bricked computers. Is there an alternative way to enter programming mode other than reset while GPIO0 is enabled?
Searching online didn't yield much hope.

No, sorry. The hardware and ROM hard-check for GPIO0.

But you could program the flash chip directly from another esp32 or spi programmer

Ooooh, that's a viable option indeed.
