The moduli space of genus $8$ Fano $3$-folds with two $\frac{1}{2}(1,1,1)$-points is rational

Let ${\mathcal{F}}_{8,2\times \frac{1}{2}(1,1,1)}$ be the moduli space of genus $8$ Fano $3$-folds with two singular points of type $\frac{1}{2}(1,1,1)$. We show that ${\mathcal{F}}_{8,2\times \frac{1}{2}(1,1,1)}$ is a rational variety.
