To answer your other questions, you would be able to charge more for the additional space, but I would think that would be negotiated when you make the modification allowing them to convert the drive through space. 

Plus “foreclosure defense” which was created out of necessity in the last crash is very useful defense in a judicial state to delay delay delay then get a low interest rate modification.

Are there any modifications to the written lease?

Being able to have zoom meetings with people that have different skills, such as experience with loan modifications and stopping foreclosures, transaction coordinators, etc. can do NOTHING except help me along my journey.

This can range from minor modifications to more extensive build-outs, depending on the nature of the tenant's business and the agreement with the landlord.

My dad was never given a notice nor was there any damn modification done to the house as said in the documents.

Assuming my lease had the right notice language on method and address, I'd be directing my attorney to challenge anything the tenant does in court because the court must enforce the lease as written and it can't be modified without a written modification (I have lease clauses for this and that the lease is an integrated contract so they also can't testify on facts outside the contract terms or that something else was verbally agreed to, etc.).
