I will answer the first part of the question "is it possible ...". Think about what it means to control emotions? This means completely controlling your own body: physiological processes, the hormonal system, the functioning of the limbic parts of the brain (which were evolutionarily formed BEFORE the appearance of the cerebral cortex, ie our limbic brain does not "think" and is outside the zone of our control). nothing can fully consciously control: neither thoughts, nor breathing, nor digestion)) You can make emotional outbursts occur much less frequently and do not greatly affect the quality of life - yes. There is research that contributes to this meditation. There are many books, such as John Arden's "Taming the Amygdala and Other Brain Training Tools" or Daniel Siegel's "The Mindful Brain. A Scientific View of Meditation".
Emotions cannot be controlled. But you have to study. When you understand what triggers this emotion in you, you kind of stop attaching importance to it.
Alas, so far nobody has succeeded. The 14th Dalai Lama admits that he is angry and irritated sometimes, and can even yell, and he has been practicing working with emotions for many years.
He also says that in order to "fight" emotions, you need them explore. To help "Atlas of emotions", which is still at the development stage, but helps to understand something (I do not know if it is in Russian).
Observe your emotions, name them, try to procrastinate (when the strongest, when weaker). You won't be able to give up emotions (and is it necessary?), But you can learn not to get carried away by them.
