The best is to ask your landlord to submit and give you a receipt.
If you want to do it in person, you will need proof of address, landlord details, etc. Check with the Phuket immigration office for the latest information. Here is the Phuket Immigration volunteer page. Seems authentic information, but with the date in 2020, not sure whether it's the latest or not.
You may be able to submit TM30 at the drive-through if they are open and you have sufficient documents.
