Donated! Glad you are branching out, doing something to spur you on, and working to keep yourself encouraged.

Use the user profiles feature of grapheneos to make a "social" profile and only use that to access Instagram / facebook.
You'll want to consider isolating IG from your primary profile, to start. The above user's suggestion hits the nail on the head.
Once the profile ks created, and you've installed IG, you'll want to deselect the option in your Manage Profiles settings on GrapheneOS to 'Allow running in the backgroud.' This way, you can ensure the app is entirely stopped until you want it open.
Another consideration may be to turn off your Bluetooth when it's not in use, as well: BT emits an 'address' of sorts that, if another IG user has enabled BT access on their IG app, may be able to detect your phone and track a conversation knowing you are in the other user's vicinity.
Is IG on a completely different profile in GrapheneOS, or is the app installed on the primary profile where you use your other apps? GrapheneOS's profiles completely isolate from one another.
It sounds like Nextcloud, an alternative to the Google services platform, may have a feature like this through their PhoneTrack app. Is that what you are looking for?
You'd have to set it up, but Nextcloud is easy to set up.

Thinkpads -- a laptop with a rich history of Linux use -- can be bought with an integrated 4090. The ThinkPad P1 Gen 6 can be configured with an i9, plenty of flexibility for drive space and RAM, and an RTX 4090. It'll run you, even used, around $3k to $4k, which is the equivalent of a desktop replacement. But it'll be pretty doggone compatible with any Linux distro you'd like.
