This past February I picked up a new Galaxy Note 8 and the first thing I did was remove the Facebook app. I have had at least four updates since that time and it is still gone.
My tablet OS updates and stuff in it comes back, so I put all the icons in a folder where I can’t see them................
But what I have read on other forums is that these software companies pay to have their apps embedded in the Android OS so that you can’t easily get rid of them.
If you do a reset, they will be back where they were when it was new.................
