The three-minute warm-up period MUST be observed and according to the rules cannot be overridden.

The three minute warm-up period is a MUST. The teams are only required to be on the field.

3-1-5 Mandatory Warm-up Activity Following Intermission: 3 minutes

(The head coach is responsible for his team being on the
field for mandatory warm-up time at the end of the scheduled
halftime intermission.)

It doesn't say that the team is required to warm-up during this time, just that they are on the field.
