What should I do for my 90-day DTV check-in in Thailand without a TM30 form?

1st 90 day DTV immigration check-in coming up for this digital nomad. I am not on soft power and/or enrolled in any classes, and provided all financial proof on my DTV application that I am in no way a financial burden to the country (I'm receiving two pensions that put me over the threshold for a DTV). The 90 day check-in is in place as basically a way to verify one's address. I am residing in a guest house in Chiang Mai, an American friend of another American expats place. It's a nice place, and rent-free. The only caveat is that I have no lease or rental agreement, nor anyway to produce a TM30 for this place at all. Please do not lecture on how the property owner is required to submit TM30, I already know that, it's simply not gonna happen. I do not have any way to generate a TM-30, or TM47 for the 90 day immigration check-in. It is just not gonna happen, period. It has been suggested to me to book a hotel for a couple of days the night before, and the night after my check-in, so my TM-30 will be live & active during that window to be in compliance with this requirement. Does anyone know for a fact, not speculation or regurgitation of the property owner is required to submit TM-30 info, again, this will not be possible, full stop. I plan to book accommodation two days, print out receipt of stay and proof of TM 30 registration from hotel, produce US passport showing entry date, copy of my DTV, and full out TM47 onsite at the immigration office, (once I have all info about hotel I'm at at time of filing). Thanks in advance for any positive & productive advice based on actual experience. Trolls, keyboard pontificators and smartasses please don't weigh in if you don't have any real-world experience with this very specific set of circumstances. 🤘😎
