Dear me. So much confusion.
First point is that the MB New Car Warranty runs for three years from date of registration, is transferable to a new owner, and requires that servicing is carried out according to the manufacturer’s published schedule to maintain cover.
The service interval for non-AMG cars is annually or 15,500 miles, whichever is soonest. The allowed leeway to maintain warranty cover was 1 month or 1,000 miles, but this was waived and extended during the COVID lockdown in 2020. I could look it up, but can't be bothered, so from memory it was extended to 3 months and 3,000 miles. In the instant case this seems to be an irrelevance because the car hasn’t been serviced since August 2020 so is well outside even the extended parameters.
Servicing does not have to be carried out by a Mercedes dealer, but when you get into grey areas that require goodwill, services outside the dealer network mean it’s less likely to be forthcoming.
My gut feel is that the most likely cause of the engine seizing was a component failure, nothing to do with whether the car had been serviced or not. However, by failing to adhere to the service schedule (late by 5 months from what I can deduce) the OP has given MB a cast iron reason to void the warranty.
