No it is not supported.
In the Scirra Admob plugin they have a (deprecated) consent screen which ask you if you are fine with seeing personalized ads or none-personalized ads. This is not enough to comply with EU law.
Even if you choose "none-personalised" ads Admob still requires to set a cookie to be able to track the ads. And the user have not give any consent for this.
This Consent dialog is deprecated since long ago.
The new UMP is in line with the ePrivacy Directive though. But with this users can opt-out for ads, obviously.
The most "important" law for consent in EU is for cookie handling, and without giving consent for cookies you are not allowed to set any.
Even though most webpages in EU now ask you for "allow cookies" and all kind of different popups, I would guess that still 95% av all webpages and apps in Europe do not comply with the EU directives.
Most other Ad-companies doesn't even provide any consent SDK at all, they just write in their documentation that they trust all app developer to fully comply with the GDPR law by themselves. Which is extremely hard for a app developer to do really.
