I recommend you ask the issuer of the visa. If it's a freezone, ask the freezone as they know your visa and your exact details. But don't ask only one time, ask several and to different people to confirm 100% is not someone having some wrong info. As the article shared before says, it depends on several factors that usually the issuer knows.
All visa stickers have the text "Visa becomes invalid if bearer stays outside UAE for more than 6 months", but this is not always applicable. Even if you have to visit only once per year, you will have that text in the visa. This information I got from several people in the freezone that issued my visa. And sorry I'm not providing more details but that is all I prefer to say publicly
Long story short, ask your visa issuer, don't trust some random internet articles
