How to strengthen Unlocked bootloader against physical attacks like evil maid?

So I have a device running lineage os and I am a little concerned about the potential data breach if my device is stolen.

My first precaution was to setup SMS findmydevice so that I could remotely control my device in case it got lost or stolen. I’m not sure how secure this is but I wanted to have a way to remotely get its location and to wipe it remotely.

The second thing I setup was locker. F-droid says that the upstream code is no longer available which is concerning but I am using it none the less. This should prevent basic attacks on the lock screen.

Is there anything else I need to do?
