hp 8200 sff upgrade path high sierra to catalina ?

i have a hp 8200 on high sierra with a 710 graphics card. it works fine, but the OS is too old to use a lot of the application i need.

i'm finding very old tutorials for installation of high sierra , but nothing on catalina or later OS versions.

is there a current (2022) install path or update path for these 8200 desktops ?

thanks !
