Can an auditor not be an artist?

Hi, this is Tuhin. I am passionate to statutory auditing as well as in authorship of story books, photography, and other artistic works. But as we know, as per the rules of the institute, an statutory auditors can not be indulge in any other professions and occupations. If an auditor is a fantastic painter or singer, can s/he not participate any singing competition or painting competition, or can he not exhibit his photography without prior approval of the ICAI? If any sincere and knowledgable person knows it, please reply.
