Any modifications invalidate the signing, so modify the development files, rebuild and resign.

I should rebuild and resign after modifed theoretically,But It very importance to solved this problem. because I have no publisher id, It is troublesome to ask other company help me to sign.It will take me a long time to sign once!

It is not theoretically anything, but practically as stated; there is no other solution: any modifications to a signed .sis/.sisx file will invalidate the signing. The only way to modify contents is by modifying the contents, repackaging it and then resigning it. The whole mechanism has been designed to detect "tampering" of signed installation packages, and circumventing it would invalidate the whole concept.

If you need to do it often and frequently, consider investing in getting your own publisher ID and learning how to do the signing yourself.

If you change a single bit in the file, it will not count as being signed any more. This is what signing is all about.
