Forgot the Power-On Password HP Omen 15-dh650nd

[ale_c]

Hi,  I hope what I read online doesn't apply to this case, few months I set up a power-on password, you know for that extra layer of security... Haven't used that notebook in a while and guess what, forgot that password and haven't noted it.
By booting up the notebook and pressing enter 3 times it will prompt me the choice to use the HP sparekey USB recovery that I don't have, nor remembering of having it set up. What I could find online I tried, booting up with either WIN + B/ WIN + V no change. I disassembled the whole thing looking for the chmos battery to finally discover that it doesn't have any. On hp support site this laptop model have no support section with software download (hoping for a bios flash or something).
I read online someone saying
