This paper serves as an extended version of our previous letterarXiv:2212.03808 [hep-th]. In this paper, we investigate the non-perturbativeand non-singular black hole solutions derived from complete $\alpha^{\prime}$corrected Hohm-Zwiebach action in different gauges (coordinate systems). Inaddition to the results that we obtained in the previous letter, we present thefollowing additional results in this paper: 1) The regular black hole solutionsin different gauges can be mutually transformed. 2) The $\alpha^{\prime}$corrections do not introduce any extra singularities beyond the event horizon.3) The event horizon remains unaffected by the $\alpha^{\prime}$ corrections.The results of this paper provide valuable illustrations for furtherinvestigation of more complicated regular black hole solutions utilizing thecomplete $\alpha^{\prime}$ in the near future.
