I guess that it depends on the disability.
DH wore hearing aids and his eyes were deteriorating. He needed a cataract op which - of course - he couldn't get during lockdown. He couldn't use tablets, etc to communicate with his family.
He developed a couple of additional health problems on top of his stroke-caused hemiparesis and I kept being asked to send in pictures electronically. The surgery would tell me to get the district nurse to examine one of the problems. The DN would say that the doctor needed to see.
The Doctor would look at the picture and tell the DN to look. In the end, we managed to book a GP visit for a week ahead. By the time the GP arrived,
my husband was on the floor waiting for an ambulance which took about 8 hrs to get here.
He survived hospital, but had to be taken off some of his heart meds because of his kidneys.
He died of a heart attack at home. I'll not go through all that - it genuinely is too traumatic - but when 'help' eventually got here, I had a house swarming with people in white suits and masks and didn't realise that some of them were police officers here to investigate the "unexpected death" of an elderly man with multiple health conditions because he'd had the temerity to die of a heart attack during the night at home instead of in a hospital.
Only when they were able to speak to our GP in the morning, would they believe that he was "under the care of a doctor".
I wasn't the only widow who experienced that. Very similar happened to another woman in nearby village. Her husband had terminal cancer and she had the same debacle, in spite of the fact that their GP had come in and certified the death.
The undertaker had already removed the body. The police entered her house and told her that she had no right to do that. (Nonsense, of course.)
The police seemed to think that they'd had an outbreak of carers murdering their patients.
