Personally out decency I think the club should at the very minimum offer a discount, but that just my opinion.
The problem is though, how many seats should they allocate as disabled seating, how long is a piece of string ?
The argument for more disabled seating could be opened up at almost any public place, buses, trains, cinemas, concerts, restaurants, the list is probably endless.
I would imagine theres an health & safety protocol that these places have to follow, just in case of an emergency evacuation ?
Is this a big club that could easily afford the discount or even to sway the cost, or a struggling lower legue club that needs every penny just to keep ticking over ?
Maybe you can write to the chairman of the club, explaining your love of football and in particular this club, also mention that you are prepared to pay, like you have done for many years, but under the circumstances is there a possibility of some sort of goodwill gesture discount, just for this season ?
You never know, he may decide to offer the seat at the disabled price or even offer one for free for the season, stranger things have happened.
Hope you get some joy.

My GP’s surgery has almost 12,000 patients on it’s list, 12,000, about 2 years ago they had a refit and built a large extension, that extended into the car park, which meant replanning the layout of the car park, they now have one, yes one disabled parking bay and 28 “normal” bays, just to add bit of insult to injury, this single disabled bay is located at the other side of the car park furthest away from the main entrance.
On a good day there might be up to 8 doctors at the surgery, without including other staff and nurses, probably another 10 people, they open the doors at 8am and they all park in some of these 28 “normal” spaces, even though theres another shared free car park at the rear of the surgery.
