How can I circumvent google play services dependencies if microG isn't an option?

• Would installing an app from APKmirror help?
• Is it safe to install apps from there at all?

UPD: Turns out for most apps there's a special notification sating for Gservices availability (on xiaomi at least) you can just turn it off

But now another question rises:

• Is disabling Gservices enough to bypass comming lockdown, or an ADB intervention is necessary?
