Can't or won't? If California can get away with its agricultural checkpoints without running afoul of e.g. the Commerce Clause, then it seems like restricting interstate border crossings is at least hypothetically possible.
In practice, it's pretty trivial to bypass those checkpoints if you really want to smuggle produce into the state (e.g. the I-80 checkpoint, where you can take the Hirschdale Road exit and follow Glenshire Drive to 287, then get right back on I-80). I highly doubt COVID checkpoints would be any harder to bypass.
