  In this work, we study the possible existence of gravitational phase
transition from AdS to dS asymptotic geometries in Einstein-Gauss-Bonnet
gravity by adding the Maxwell one-form field ($A_\mu$) and the Kalb-Ramond
two-form field ($B_{\mu\nu}$) as impurity substitutions. The phase transitions
proceed via the bubble nucleation of spherical thin-shells described by
different branches of the solutions which host a dS black hole in the interior
and asymptotic thermal AdS state in the exterior. We analyze the phase diagrams
of the free energy and temperature to demonstrate the existence of the phase
transitions in the grand canonical ensemble (fixed electrical potential). The
phase transitions of having the one-form and two-form charges are possible in
which the critical temperature is lower than that of the neutral case.
Comparing results with existing literature, more importantly, our analyses show
that the critical temperature and the Gauss-Bonnet coupling $\lambda$ of the
phase transitions get decreased by adding more types of the charges.
