LibreOffice's Format > Paragraph > Text Flow checkbox. Only "off" travels (Word has no per-paragraph "on") and only under a document that hyphenates, or it would say what is already true. ODF writes fo:hyphenate="false" into the paragraph's text properties, DOCX gains w:suppressAutoHyphens through a post-pack pass — the docx package exposes no option for it. Both survive a LibreOffice re-save.
