Marta,
Not by default; however, the Consent Manager code can be fully customized and its code is accessible from the TIQ interface, which means it would most likely be possible to achieve your use case after further review.
If the profile is set up for three brands from the same domain (for example), the customization would be fairly straightforward within the HTML, CSS, and JavaScript editor sections of the Consent Manager. The code would have conditions such as: if brand1 is found, show the HTML code and CSS for brand1 section, etc.
If the profile is set up for three brands with different domains, here it becomes more challenging to develop. The three domains have their own cookies persisting data from the user consent data required for the Consent Manager.
Moving forward with this sort of solution requires intermediate/advanced JavaScript skills, and expertise within TiQ. If it's something you're interested in further pursuing, I'd recommend reaching out to Tealium Support. One of the engineers will be able to assess your situation to determine the best path forward.
Thanks.
Mike
