Where can I go for help with Adobe Portfolio?

I want prospective clients to find and view my portfolio while opting out of having my work collected for generative AI training.

Does Adobe Portfolio offer a way to add or edit robots.txt rules for specific crawlers, such as:

User-agent: meta-externalagent
Disallow: /

User-agent: GPTBot
Disallow: /

User-agent: ClaudeBot
Disallow: /

User-agent: Google-Extended
Disallow: /

I want to keep ordinary search engine indexing enabled. I understand these directives depend on crawler compliance and cannot prevent all scraping.

If custom robots.txt rules aren't supported, does Adobe Portfolio provide an equivalent AI opt-out setting or another supported method?
