How to suppress alerts in Azure monitor during patching cycle based on tagging

I have 20 VMs, and there are 3 maintenance configuration windows. Alerts are being configured with Azure Monitor and are added on the subscription level.

I want to suppress the alerts triggered during the patching window. VMs are bifurcated and are added to the maintenance configuration groups based on Tagging.
Maintenance windows are 3rd Tuesday, 4th Saturday, and 2nd Monday of every Month.
I am not able to utilize only the alert processing rule to achieve this.

Is there any other way I can suppress all the alerts raised during the maintenance window, since I want to avoid manual intervention?

    Hello needHelp

    1. Create a Processing Rule for Each Schedule
      • For every patching schedule, define a separate processing rule to manage alerts and actions.
    2. Define Scope and Filters
      • Within each rule, select the scope to target only the VMs scheduled for patching on that specific day.
      • Apply relevant filters to narrow down the selection

    3. Set Frequency and Day
      • Configure the rule to run on a weekly basis, selecting the appropriate day that matches the patching schedule.

    1. Finalize and Create the Rule
      • Review the configuration and create the processing rule.
    2. Manage Alerts Around Patching Cycles
      • Before patching starts, enable the alert to monitor patching activities.
      • After patching completes, disable the alert to avoid unnecessary notifications until the next cycle.

    It is not a practical solution for a large fleet of VMs with so many maintenance configurations.
    There should be an option to disable the alert automatically during the maintenance window.
