Tag Manager integration without Pushing default & Update

Hi,
due to the usage of custom tags alongside the main Iubenda plugin, I am wondering if there's any way to implement Iubenda using tag manager in a way that the Iubenda tag does not directly touch consent settings, and consequently only
a- Shows the banner & other graphical elements in a functional way
b- Sets the iub cookie
c- Records consents on that cookie

It must NOT
a- Push default consent on tag manager (using Google API)
b- Push consent updates on tag manager
