This answer essentially is a more detailed version of the comments, essentially finding that what you want to do is not possible.

You ask for a way to

Certify Document when Approval Signature exist

According to the current PDF specification:

Thus, you cannot validly add a certification signature to a PDF which already has approval signatures.

(This does not automatically mean that all validators will detect the issue if you add a certification signature after approval signatures, let alone correctly display the cause. Many validators only do a subset of the checks that strictly speaking are necessary...)

More question if the certification signature come first then next is approval like 3 signature approval, can the last the certification setMDPPermission with 1 ? so at the end the document can't add more approval signature

setMDPPermission adds a DocMDP transform to the signature, and such a transform makes the signature a certification signature. Thus, using this method when signing a document that already has an approval signature, will create an invalid PDF or fail entirely.

You can lock a PDF document with an approval signature, though, if you add a Lock dictionary to the signature field with a P entry of 1. Beware, though, this is a ISO 32000-2 feature originally introduced as a feature of an Adobe Extension to ISO 32000-1. Not all PDF viewers support ISO 32000-2 yet, so some viewers may not respect this entry.
