So I looked for an idea how to get into programming mode from away and I found those relay modules with high level trigger.
They are available at ebay or aliexpress but be careful to get one which has an high level trigger (reacting from 3V) and is opto-isolated.
For example this one: https://www.aliexpress.com/item/33050592084.html

Then if you want to program you can set your connected Pin to high with a bash command.
