That will depend on the device that’s used. If it’s a Linux device, they can’t do squat. Plus, if one has a phone with GrapheneOS (which I think won’t count for this anti-4A law, but I could be wrong), that’s also how one could bypass this requirement.
And for how long can they do that is my question to you
It might end up being temporary, but I’m sure this will be fought… but the courts won’t budge on the matter, so the only other way I see it being done is orgs like the EFF and others fighting it. I’d like to see Texas officials humiliated at what they just passed by them… and maybe, just maybe, realize 4A is there for a reason.
