How to say that there is no peas? Countable or Uncountable? [closed]

The question is based upon a false assumption:

Since the vegetable 'peas' can be countable and uncountable,

Absent an example of "pea" as uncountable, the question fails.

*There......is........n't...................{any peas}.

Adverb...verb negation {plural noun phrase as subject}

In English, the verb and subject agree in number.

There aren't any peas. - Correct.
