Diophantine approximation by primes and Landau--Siegel zeros

Let $α>0$ be an irrational number of finite type and let $β\in\mathbb{R}$. Assuming the infinitude of Siegel zeros (respectively, sufficiently strong Siegel zeros), we show that for every sufficiently small $\varepsilon>0$, there exist infinitely many primes $p$ such that \begin{gather*} \|αp+β\|\
