Unfortunately Chrome for Android does not allow that feature.
You can download an app, Firefox for Android. It's slower than Chrome, but another browser option.
Then, in Firefox, paste this link to install the add-on to stop animated gifs:
https://addons.mozilla.org/en-US/and...animated-gifs/
If you can't paste just google Firefox for Android stop animated gifs
Click on View Full Site
CLick on Donwload
In Firefox, go to the 3 Dots at the top, Tools, Add-ons
Select Toggle animated GIFs
Check Pause Gifs by default
That should work.
