Clearing the definition of an environment

I need to render the minipage environment ineffective (the reason is that I need to sometimes compile latex documents for a visually impaired reader with a huge point size, not compatible with the general layout of the document).

renewenvironment{minipage}[1]{relax}{relax}

fails because of the optional arguments sometimes passed to begin{minipage}

I guess I can use renewcommand on minipage and endminipage to adapt their definitions from latex.ltx but I was wondering if there isn’t a more straightforward way to do it.

 RenewDocumentEnvironment{minipage}{ o o o m }{}{}
