How to install Frigate v12?

i just installed v14 and it is not stable with my machine. also UI is confusing. how can i revert back to my v12?

i just tried to restore from my Backup but this does not work. i believe it only restore config files.

i see the source code is here Release Release 0.12.1 · blakeblackshear/frigate · GitHub
how can i tell HA (HA OS on nuc)to install this version of the Add-On instead of v14?

is there a repo for v12 of this Add-on? or source code so i can create my own repo to install?
v14 uses too much resources and crashes my Celeron cpu
