Type-II Weyl semimetal MoTe$_2$ exhibits a first-order structural transitionat $T_s$ $\sim$250~K and superconducts at $T_c$ $\sim$0.1~K at ambientpressure. Both $T_s$ and $T_c$ can be manipulated by several tuning parameters,such as hydrostatic pressure and chemical substitution. It is often reportedthat suppressing $T_s$ enhances $T_c$, but our study shows a differentbehaviour when MoTe$_2$ is hole-doped by Ta. When $T_s$ is suppressed by Tadoping, $T_c$ is also suppressed. Our findings suggest that the suppression of$T_s$ does not necessarily enhance superconductivity in MoTe$_2$. By connectingwith the findings of electron-doped MoTe$_2$, we argue that varying electroncarrier concentration can effectively tune $T_c$. In addition, the Hallcoefficient is enhanced around the doping region, where $T_s$ is completelysuppressed, suggesting that the critical scattering around the structuraltransition may also play a role in suppressing $T_c$.
