We consider singular SDEs like \begin{equation} \label{ss} dX_t = b(t, X_t) dt + A X_t dt + σ(t) d{L}_t , \;\; t \in [0,T], \;\; X_0 =x \in {\mathbb R}^n, \end{equation} where $A$ is a real $n \times n $ matrix, i.e., $A \in {\mathbb R}^n \otimes {\mathbb R}^n$, $b$ is bounded and Hölder continuous, $σ: [0,\infty) \to {\mathbb R}^n \otimes {\mathbb R}^d $ is a locally bounded function and $L= ({L}_t)$ is an ${\mathbb R}^d$-valued Lévy process, $1 \le d \le n$. We show that strong existence and uniqueness together with $L^p$-Lipschitz dependence on the initial condition $x $ imply Davie's uniqueness or path by path uniqueness. This extends a result of [E. Priola, AIHP, 2018] proved when $n=d$, $A=0$ and $σ(t) \equiv I $. We apply the result to some singular degenerate SDEs associated to the kinetic transport operator $ \frac{1}{2} \triangle_v f + $ ${v \cdot \partial_{x}f} $ $+F(x,v)\cdot \partial_{v}f $ when $n =2d $ and $L$ is an ${\mathbb R}^d$-valued Wiener process. For such equations strong existence and uniqueness are known under Hölder type conditions on $b$. We show that in addition also Davie's uniqueness holds.
