Hi [Madhukar k] Madhukar k,

There are two way to deactivate the Trigger directly in prod
1) Create custom setting to activate or deactivate trigger (Best One)

2) You can also do the same by eclipes. Please check below post

Important: You must consider the consequences of disabling a trigger in the production environment during work hours. It is highly recommended to perform this work outside normal business hours and to disable access to the application to non administrators during the maintenance period.

Follow these steps:
1) Disable the trigger on the sandbox environment
2) Create a new project in Eclipse using the Sandbox and including the trigger (or refresh your existing Eclipse project)
3) Alternative: edit the triggername.trigger-meta.xml in an existing project and change the status node to false: <status>Inactive</status>
4) Save the change locally
5) Deploy the trigger to production
6) Complete the data load
7) If the change is not permanent or you want to enable the trigger again then enable the trigger by making it active on the sandbox or project again and deploy it to production

Please let us know if this will help you
