Is it permissible to refrain from visiting one's maternal uncle's house to avoid the forbidden shaking of hands with his daughters?

The prohibition of a man shaking hands with a non-mahram woman is religiously established. If visiting the uncle's house leads to committing this sin, then one can refrain from visiting and maintain ties with them through other means, as kinship ties do not have a specific method. However, the easier option is to visit the uncle's house and refrain from shaking hands with his daughters, explaining the reason without embarrassment, for praiseworthy modesty is that which prevents one from falling into prohibitions.
