Hi Mandapaka,

Greetings to you!

Yes, you can deploy the permission set. In API version 40.0 and later, when you retrieve or deploy permission set metadata, all content exposed in Metadata API for the permission sets is included. The metadata includes Apex associated with the permission set, CRUD, and so on.

In API version 39.0 and earlier, retrieving or deploying permission set metadata returns only app and system permissions assigned to the permission set. Junction metadata (such as Apex, CRUD) are included only if the metadata for the related component is also included in the package definition.

Please refer to the below links which might help you further with the above requirement.
