Question

This style don't work:

.custom-control-input:disabled ~ .custom-control-label::before {
    cursor: not-allowed;

Answer 1

For disabled custom-control elements in Bootstrap 4 (checkbox, radio button), you need the following selector css rule/selector:

.custom-control-input:disabled ~ .custom-control-label {
    cursor: not-allowed;
}

And if you wanted the custom cursor style only for the actual checkbox/radio button but not for the label (not recommended in this case), then you'd need this rule:

.custom-control-input:disabled ~ .custom-control-label::after {
    cursor: not-allowed;
}
