Schedule Google Play Updates

I tried running my phone without GApps but very quickly realised that I needed access to Google Play.
There are ways to download apks from the Play store without an account but then you never get any updates.

I am not philosophically opposed to the Google services but I am trying to reduce the number of background apps running.

Is there a way to freeze and only turn on Google Play services when opening the Play store and once a week to check for updates?
