Current behavior
The only way to disable a single radio in Angular currently is to set it on the radioButton itself. I can't set it on the control object. But:

<p-radioButton name="a" value="a" formControlName="ctrl"/>
<p-radioButton name="b" value="b" formControlName="ctrl" [disabled]="true"/>

Gives warning:

It looks like you're using the disabled attribute with a reactive form directive. If you set disabled to true
when you set up this control in your component class, the disabled attribute will actually be set in the DOM for
you. We recommend using this approach to avoid 'changed after checked' errors.

Example:
form = new FormGroup({
first: new FormControl({value: 'Nancy', disabled: true}, Validators.required),
last: new FormControl('Drew', Validators.required)
});

Expected behavior
No warning

What is the motivation / use case for changing the behavior?
I don't like warnings.

I hope this time it isn't immediately closed again like https://github.com/primefaces/primeng/issues/9143. I tried [attr.disabled] but that is ignored by p-radioButton.
