The to_tag is going to appear for any message beyond the initial request. Short answer, no, you can't hide the to_tag. It's very important to the SIP message.
Still, if you want to change the to_tag to something different, you could use B2BUA-based topology hiding[1]. You will need a separate OpenSIPS instance for this. Dialog-based topology hiding[2] may obfuscate the to_tag as well. From the doc page it doesn't appear so. I'll include it for completeness. Why you want to hide the to_tag?
