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