Can you? Yes. will it? No.
You could use a windshield (windscreen) repair kit. If the cracks aren't bad, it might make them almost invisible. It it's a spiderweb crack, at least it will hold all the glass together. (It won't shoe as much but it will still show.) Make sure you get a lot in the cracks, so they're overflowing, and if you don't have a UV lamp, expose to the noon sun for half an hour (11:45 to 12:15 standard time, so adjust for your timezone). That's if the touchscreen still works. Repairing the cracks in the glass won't make a dead touchscreen start working.
