Can Meta tags fire even with marketing cookies denied? Moving from Hard Blocking to Modeling (web and server Google Tag Manager)

Hello everyone,

I am managing GTM for an EU-based company (strict GDPR compliance). I’ve implemented a manual Consent Mode setup using a custom banner.

Currently, I use "Hard Blocking" for all Meta tags (both Web and Server) when marketing cookies are denied. However, I’d like to move toward a setup similar to Google’s Advanced Consent Mode (anonymous pings for conversion modelling already built in GA4 and Google Ads tags).

Web GTM: I use the official Meta Pixel template. It has a field "Consent Granted (GDPR)" that I can toggle. If I set this to false based on the user's choice and let it fire when consent is denied, will Meta treat this as an anonymous signal for modeling, or is this still a compliance risk?

Server-Side GTM: I use the facebookincubator Conversions API Tag. Unlike the web template, it doesn't have a native "Consent" field. Should I manually map parameters like ad_user_data and ad_personalization to granted/denied within the tag's parameters (or via Transformations) to enable modeling? Or is it safer to stick with hard-blocking for Meta on the server side?

Basically, I want to know if Meta now has a formal "Advanced Consent Mode" that allows for data modeling without violating GDPR when ad_storage is denied.

Thanks for any insights!
