I was looking for information on web, but couldn't find any information how to do it. Everyone was saying it's impossible.
But I found the way how to do it. So, download tactics and/or shortlists as usually.
Open folder:
for tactics: C:\Users\*user-name*\AppData\Local\Sports Interactive\Football Manager 2023 Console\Temporary\add_ons\tactics
for shortlists: C:\Users\*user-name*\AppData\Local\Sports Interactive\Football Manager 2023 Console\Temporary\add_ons\shortlists
copy your file in correct folder and IN PROPERTIES PUT IT AS READ ONLY.
It will work as normal!
