A finiteness result on representations of Nori's fundamental group scheme

Let $(X,x)$ be a pointed geometrically connected smooth projective variety over a sub-$p$-adic field $K$. For any given rank $n$, we prove that there are only finitely many isomorphism classes of representations ${\pi }_1^{EF}(X,x)\to {\mathrm{G}\mathrm{L}}_n$, where ${\pi }_1^{EF}(X,x)$ is Nori’s fundamental group of essentially finite bundles. Equivalently, there are only finitely many isomorphism classes of essentially finite bundles of rank $n$. This answers a question from C.Gasbarri.
