You have a consistency problem.
First you claim that the President can't call up the Guard and then you say that he did.
You're wrong on both counts
Some Republican governors contend they have the right to let National Guard members in their states refuse vaccinations. Do they?

In the 1980s, for instance, several governors who opposed the Reagan Administration's policies in Central America objected to calls for Guard members to go there for training. Minnesota Gov. Rudy Perpich filed suit, and in 1990,
the U.S. Supreme Court ruled that federal authority prevails when the issue is activation.
As far as Trump calling up the guard...he made one comment to Sec Defense Chris Miller which Miller ignored.
There was never a written or formal authorization by Trump
