Yes it is, there is a module in the appstore for it: https://appstore.home.mendix.com/link/app/2558/
or check out this forum post: https://forum.mendix.com/link/questions/92637
What exactly do you want to achieve?
If you want to switch the language of the user in a microflow: yes that is possible, the change however will be in effect after signing out and logging in again(there are possibillities to automate this behaviour with a java action for example).
Do you want to get the value of a label in a different language in a microflow? I don't think that is directly possible.
