Hi Thyago,
EXOS switches allow you to get DSCP as a matching condition, and you can take replace-dscp as an action that will replace DSCP value from the header with one from associated QoS profile, or replace-dscp-value can also be the action so it should be ok (I didn't play with it yet).
Please take a look below, you may find what matching criteria can be used (every single row shows compatible combinations.

For further info, you might like to take a look at ACL chapter in EXOS User Guide:

Hope that helps,
