LaTeX Change Default Section format

The following code demonstrates the default \section heading along with a custom \tcolorbox. I would like to alter the \section default to utilize the custom \tcolorbox function.

How can I change the default \section format to the customized \tcolorbox?

\documentclass[letter,10pt]{article}
\usepackage[utf8]{inputenc}

\RequirePackage[margin=.5in, top=.5in, bottom=1in]{geometry}
\raggedright\raggedbottom

\RequirePackage[most]{tcolorbox}

\newtcolorbox[auto counter]{SectionEnv}{
    enhanced,
    sharp corners=uphill,
    colback=gray!50,
    colframe=black,
    coltext=black,
    arc=3mm,
    boxrule=1mm,
    boxsep=1mm
}
\begin{document}

\section{Default Section Heading} % <-- default section heading

\begin{SectionEnv}

    \textbf{Desired Section Heading}

\end{SectionEnv}

\end{document}

Output of current code:
