Unfortunately, that is not possible. Everything that is on the Internet can also be downloaded.
You can at most make it more difficult for “normal” visitors to your website to want or be able to save the images.
For example, you could put a watermark on all images and thereby mark them with you as the source. There are also plugins for this: https://projectdmc.org/plugins/tags/watermark/
Or you can add a right-click lock. This may be effective enough for some users, but it is also easy to bypass if you know how. There are also plugins for this here: https://projectdmc.org/plugins/search/right+click/
Another aspect is searching on Google. Your images can usually be found there too. You can prevent this by preventing the indexing of the /wp-content/uploads/ directory using robots.txt. If you have an SEO plugin, there may also be an option for this. You can certainly report this in the support forum of your SEO plugin.

Thank you, I have implemented both, disabled right click and added watermark, hopefully that will help protect my content.
Thank you
