This is an xkb_symbols option to swap the Pause and Delete keys for the HP Omen 15 2020 keyboard.
Following the instructions here https://unix.stackexchange.com/questions/212573/how-can-i-make-backspace-act-as-escape-using-setxkbmap/215062#215062 I was able to create a new symbol pause (see pause file in this gist), and add it to the evdev and evdev.lst files and then with the following command perform the remap:
setxkbmap -option pause:swapdelete
me too, never buy anything from hp again
