Is it possible to disable hyphenation only for TOC?

Question

I want to keep hyphenation across the document but to be disabled in TOC

\makeatletter
\renewcommand{\@tocrmarg}{2.55em plus1fil}
\makeatother

Here is the MWE

\documentclass[a4paper,12pt]{report}
\usepackage{geometry}
\geometry{margin=2.5cm}
\usepackage{kantlipsum}
\linespread{1.2}
\usepackage[titles]{tocloft} %clear page TOC
\newcommand\Dotfill{\cftdotfill{\cftsecdotsep}}
\renewcommand{\cftchapleader}{\cftdotfill{\cftsecdotsep}}
\setcounter{secnumdepth}{-1}
\setcounter{tocdepth}{4}
%----------hypenation---------------------
\usepackage{hyphenat}
\emergencystretch=10pt      % allows some extra whitespace per line.
\exhyphenpenalty=100        % allows using hyphens which were already present.
% \hyphenpenalty=10000        % disables hyphens completly.
%-------------Title Chap & Section------------------------
\usepackage{titlesec}

I'm looking for an elegant way to show the TOC, meaning to show that chapters are belonged to the Part. Hyphenation is an ugly way for me. I'm open to any suggestion that will display an elegant TOC for a collective document.

Does that work? https://tex.stackexchange.com/questions/132266/how-to-turn-off-hyphenation-in-toc-only — Ingmar, Oct 22 '21 at 10:31
@Ingmar unfortunately is not working for me. I also tried \begingroup \RaggedRight \tableofcontents \endgroup and is not working — Mafsi, Oct 22 '21 at 10:36
Why do you think that \RaggedRight disables hyphenation? Are you maybe confusing it with \raggedright? — Mico, Oct 22 '21 at 10:47
@Mico I found it here and I tried> https://tex.stackexchange.com/questions/139740/hyphenation-in-a-table-of-contents-causing-bad-blocks — Mafsi, Oct 22 '21 at 10:50
@Mafsi -- Please note what I wrote below the accepted answer in the link you provided: "The \RaggedRight [command] won't prohibit all hyphenation. To really turn off all hyphenation in a flush-left setting, use \raggedright (note: no uppercase letters)". Still don't believe me? Here's an excerpt from the abstract of the user guide of the ragged2e package (which provides the \RaggedRight macro): "This package provides new commands and environments ... which are easy to configure to allow hyphenation." — Mico, Oct 22 '21 at 11:04
@Mico I'm open to any suggestion that will make a TOC elegant. I'm not good in LaTeX, so I found how to use tocloft today. If there is any way to make Chapters indented in order to show belonging to the Part, I can accepted — Mafsi, Oct 22 '21 at 14:05

Try this in your MWE, for which thank you.

\bgroup    % keep non-hyphenation local to the ToC
\hyphenpenalty=10000
\tableofcontents
\egroup

Processing your MWE shows that chapters are indented wrt to parts in the ToC, so you already have that.

Thanks a lot! Never thought of that, although it was in front of my eyes! – Mafsi Oct 22 '21 at 17:11
