No, but you also need to load the def files:

\documentclass{article}
\usepackage[greek]{babel}
\makeatletter
  \renewcommand*{\greekfontencoding}{TU}
  \renewcommand*{\bbl at greek@fontencdef}{greek-euenc}
  \renewcommand*{\LastDeclaredEncoding}{TU}
  \InputIfFileExists{\bbl at greek@fontencdef .def}{}{} 
\makeatother  
\begin{document}
\MakeUppercase  {\textalpha }
\end{document}
