hi @JANARTHANAN RAVICHANDRAN Please create Record-trigger flow on your desired object (where you want to change the Name field) with following details

Initial condition

PickList_Field__c EQUALS High

and choose Fast Field Update from option

then follow below steps inside flow

1. Create one New Resource Variable of Type as TEXT and Default Value will be

let say your new resource variable name is changedCourseName

'High Priority '+ $Record.Name

2. Use Assignment Element and do the following

$Record.Name EQUALS changedCourseName

Voila! you are done.
