There are certainly mortise-form-factor smart locks; I installed one of them last year. They tend to be commercial-grade rather than home-grade; more durable and able to handle more complex programming but also more expensive.
At one point several manufacturers were offering smart mortise cylinders, which did a digital handshake with a powered key to make the key extremely difficult to duplicate. Thay would install into your current latch mechanism. But I presume that isn't what you:re looking for.
If you were a paying customer I'd ask you to be more specific about what you need and then do a search thru the manufacturers. A full-time locksmith would be more aware if current product lines and would find the answer faster.
At 24mm, the holes do not reach the actuator.
If you carefully examine the sides of the drilled holes, you should be able to see the remains of the nickel-plated anti-drill pins. If you don't see them, your lock is probably ABH-I.
I think the first thing to try is to remove one of the cores completely. Drive a hardened steel screw into the key slot and pry the core out with a claw hammer or pry bar (aka crowbar).
You will need to push a metal plug or tool into the drilled hole to keep the core from turning while you force the steel screw into the key slot. Obviously the screw should be a star drive, or even a hex head if you can find one. Try to get it at least 15mm into the core.
It looks like you should try the indoor side first, as you can use the lock housing as a fulcrum without crushing the door panel. Use a scrap of plywood to protect the door when prying.
If you can't get either core out, the next best thing would be to drill all the way through both cores and the actuator. Don't just extend the existing holes at their current diameter -- unlike the original driller, you are not trying to cut away working parts of the lock -- but use a much smaller drill size. You only need a hole large enough to fit a steel rod, like a piece of bass piano wire. Or, you may be able to use the drill itself to tie the cores to the actuator.
Add an assistant and a little coordination to turn both cores in the same direction at the same time, and the door should open with minimum fuss.

Look for reducer or adapter plates. They’re a pair flat rings that go on both sides of the door hole. The outer diameter is big enough to cover the hole completely and the inner diameter is sized for the lock.
They’ll have basic ones at any home store. Usually in brass and satin nickel finishes.
