  Recently, it is found that the strong cosmic censorship (SCC) is violated in
RNdS black hole by a minimal coupled neutral massless scalar field at the
linear perturbation level. For the Einstein-Maxwell-Scalar-Gauss-Bonnet theory
which is famous for the spontaneous scalarization phenomenon, there exists the
scalar field coupled with the Gauss-Bonnet term. Whether the SCC of the RNdS
black hole can be repaired by the non-minimal coupled scalar field perturbation
at the linear level becomes an interesting question. In this paper, we firstly
investigate the extendibility of the metric beyond the Cauchy horizon in the
Einstein-Maxwell-Scalar-Gauss-Bonnet theory. Then, we examine the SCC of the
RNdS black hole by calculating the quasinormal mode of the non-minimal coupled
scalar field and find that the SCC can be recovered under some parameters.
