Question about GSC and noindex tag

hey gurus, I have an issue with a client's website that is a bit challenging. They have two pages that are not indexed by google. When I check on GSC I get this message: Page is not indexed: Excluded by ‘noindex’ tag I've checked the code, inspected it, and there is no "noindex tag". I've checked robots.txt and nothing. Is there anyone keep to share any tip to find this? TIA
