No. “点儿” is not an adverb.
In the sentence 你要多穿点儿衣服, 多 is the adverb meaning “more,” while 点儿 means “a little” or “a bit” and indicates a small amount.
The pattern is:
多 + Verb + 点儿 + Object
Examples:
多穿点儿衣服。(Wear a little more clothing.)
多喝点儿水。(Drink a little more water.)
多吃点儿水果。(Eat a little more fruit.)
Together, 多……点儿 means “a little more…” and is a very common pattern in spoken Mandarin.
