XPS 8700 Bios Upgrade Intel PTT

Hello,

I have an XPS 8700 computer. I know it is fairly old but I got it running Windows 11 (using an override method to bypass TPM requirement) quite well with 32GB of RAM and an SSD so it works for me. I would like to unlock the Bios with the computer to enable Intel PTT. Supposedly this is an option but it is not listed in the bios. I saw an old thread here that mentions someone unlocking the bios for this computer: https://www.bios-mods.com/forum/Thread-R...-8700-Bios I also have been following this old thread about enabling PTT: https://www.dell.com/community/XPS-Deskt...rue#M62832

Simply put if I flash the bios the previous person uploaded would this work for my PC?

Thanks!
