BIOS supervisor password

My laptop is acer aspire e5
I set bios supervisor password and forgot. I tried various methods like biospw code entering thing but after accessing BIOS all options are grey. I took out CMOS battery for an hour but that didn’t work too. I have ubuntu 20.10. one more method I saw was jumper shorting but I couldn’t find any jumper
Please suggest a way to change boot priority and access bios
Please 🥺
