You can enable Viva Insights to set focus time up for your account by choosing to configure your focus plan. This will add 2 hours of focus time by default to your calendar as possible on a recurring basis. You can alter the amount of time and notification preferences in the same area.
To disable the automatic scheduling of a focus time hold, you will need to leave plan within the same Protect Time settings area of Viva Insights.
