Currently I am a student on F1 visa, and got approved for h1b consular processing can i change it after approve to change of status ?

Unfortunately there is no changing an H-1B from consular processing to change of status in the US when it has been approved. Your choice appears to be going through the consular processing or having the employer refile the H-1B package all over again with the request for change of status.
