Abstract	In this talk, the latest measurements of $\| V_{u b} \|$ and $\| V_{c b} \|$ by the Belle II collaboration are presented. These results are based on 189 fb $^{- 1}$ of Belle II data recorded at the $Υ (4 S)$ resonance. We report measurements with inclusive and exclusive $B$ decays. Two main strategies are employed for these results, one where the other $B$ in the event is exclusively reconstructed (tagged) and another where the other $B$ is not (untagged). We also report on a novel approach to measuring inclusive $\| V_{c b} \|$ by determining the $< q^{2} >$ moments of $B \to X_{c} ℓ ν$
