Understanding and simulating non-Abelian quantum spin-liquids and dimer models is an open challenge in the condensed matter and high energy physics landscape. Recent advancements in the field of quantum simulations have significantly expanded its potential for applications, particularly in the context of lattice gauge theories (LGTs). Nevertheless, maintaining gauge invariance throughout a simulation remains a critical challenge, especially for large-scale non-Abelian LGTs. We propose a novel approach to simulate non-Abelian U(N) LGTs with dynamical fermionic matter in (2+1) dimensions, enhancing the reliability of the simulation through the suppression of the occupation of gauge invariant sectors. We present a comprehensive framework to simulate gauge-invariant dynamics and we propose two experimental platforms -- utilizing ultracold alkaline-earth-like atoms and Rydberg-dressing -- to implement these models, enabling the quantum simulation of large-scale non-Abelian gauge theories in near-term experiments.
