It is not merged now for V16 but the Pull request is already created for "auth_session_timeout".

This will cover your needs as soon as it is available in OCA repo.

You should also be able to adapt the "http.py" of odoo to your needs.

There are also some modules available in the App store... Just look for "session timeout" or "User Login Security". You can check if one of those is sufficient for you.

Hope this helps

in odoo.conf

session_timeout = 3600000000
