We calculate the renewed phonon bands and mode-Gr"uneisen parameters for the $Pm\overline{3}m$ phases of $B{\mathrm{F}}_{3}$ ($B=\mathrm{Sc}$, Y, La, Al, Ga, In) including the nonanalytical term correction, as well as the mode-Gr"uneisen parameters for the $R\overline{3}c$ phase of $\mathrm{Sc}{\mathrm{F}}_{3}$ under hydrostatic pressure derived from the six different types of strains, all of which are based on the comments by Dove and Phillips [Phys. Rev. B (2025)]. As a result, we show that there is no significant change in the discussion given in our original publication [Phys. Rev. B 110, 064104 (2024)]. However, we acknowledge that the disappearance of the negative thermal expansion (NTE) behavior in the $R\overline{3}c$ phase of $\mathrm{Sc}{\mathrm{F}}_{3}$ cannot be solely explained by the less negative Gr"uneisen parameters of the $Pm\overline{3}m$ phase of $\mathrm{Sc}{\mathrm{F}}_{3}$. We denote that we did not claim that the NTE behavior of $\mathrm{Sc}{\mathrm{F}}_{3}$ is not well understood, and the most important point of our original paper is that we have explained the dynamical stability of the cubic $\mathrm{Sc}{\mathrm{F}}_{3}$ by the group theoretical analyses of the electronic and phonon band structures.
