Yes, that is correct. In the sentence, "very" is an adverb modifying the adjective "unpopular," and "more" is an adverb modifying the adjective "conventional." Adverbs are words that provide more information about verbs, adjectives, or other adverbs. They often answer questions such as how, when, where, why, or to what extent. In this case, "very" tells us the extent to which he is unpopular, and "more" tells us to what extent his neighbors are conventional.
