Hello Jake,

I also consider DisabledDates very useful and a must-have feature for the DateTimePicker component as well.

We currently have another feature request for supporting disabled time frames which will cover your desired scenario, too. That said, I have marked this thread as a duplicate of the previously opened one, so they will be linked. You can find the other public request here - Allow support for disabled time frames.

I already added your vote there to increase its popularity as we are prioritizing the feature requests implementation based on the community interest and demand. You can also follow it to receive email notifications when its status changes. This is the best way to keep in track with the progress of the feature as once we know which release will contain its implementation, we will update its status in the feedback portal and you will be notified via email accordingly.

Regards,
