Yes and no, Cheatengine will require a high level of process manipulating including hooking many functions that involve the detection of specific HWND's such as cheatengines...
For the SpawnShield scan you will need to find the pointer toward the CharacterFX class which contains the Spawnshield offset.
What exactly do you need it for? Why not just use characterFX class and check to see if its enabled?
If I remember correctly. Don't quote me if I'm wrong.
Even if you have the class and pointers to the spawn shield.
Example like making the spawn shield never ending. thus godmode.
It would only be a client side change. Spawn Shield is server sided.
