As early as the last Trump presidency I was seeing people with good opsec doing the following.

1. Backup your device to the cloud (a different cloud than the default if possible)

2. Erase your device

3. Provide your empty / near empty device for inspection.

4. Load the backup after the airport checks.

It might be wise to update this with some basic changes, like creating fake accounts that are auto signed in on your device. Blank twitter account, blank gmail account etc.
