Is there a dogmatic or theological (yet not dogmatic) justification for kneeling before a statue/icon of the Virgin Mary?

We Catholics keel when praying in front of an icon representing God (e.g. a statue of Jesus, or a crucifix as in some confessionals), or during an Eucharistic Adoration. However, some people also kneel in front of a statue depicting the Virgin Mary (or that of some saints). I do understand that, theologically speaking, proper veneration of Mary and saints does not represent idolatry, but kneeling seems to be, in my opinion, something reserved for God alone. As [Philippians 2:10](https://www.biblegateway.com/passage/?search=Philippians+2%3A10-11&version=NIV) says: >that at the name of Jesus every knee should bow, in heaven and on earth and under the earth So, beyond a justification based on mere cultural practices or habits, is there a dogmatic teaching of the Magisterium, or a theological justification (yet not dogmatic) stating that kneeling to venerate Mary is a "valid" practice? As far as I understand, dogmatic teachings only pertain to issues of faith and morals, meaning the justification for it might not be found there. There are two questions ([here](https://christianity.stackexchange.com/questions/61165/how-do-catholics-answer-the-question-of-idol-worship-within-the-faith) and [here](https://christianity.stackexchange.com/questions/27027/why-do-catholics-bow-for-icons-of-the-virgin-mary)) which are related to the issue of veneration of saints/Mary, and of bowing to Mary. But there are not specific in details regarding kneeling (which in my view is much stronger than bowing).
