In theory there isn't. In practice > 99% of the website I visit have a cookie banner thingy. Including the EU own website (https://european-union.europa.eu/index_en).
Think about it: even a government agency isn't able to produce a simple static web page without having to display that cookie banner. If their definitions of "bad cookies that require a banner" is so wide that even they can't work around it to correctly inform citizens, without collecting any private data, displaying any ad or reselling anything; maybe the definition is wrong.
For all intent and purposes, there is a cookie banner law.
They could not have a cookie banner, but their privacy policy states pretty clearly why they want your consent. It is to "gather analytics data (about user behaviour)".
Additionally you don't need to consent to this and can access everything without them "collecting any private data, displaying any ad or reselling anything". The only reason they ask for consent is to gather analytics, which is similar to you being asked for your postal code when paying while shopping.
