Is there a way to disable video assistant's ability to save videos?

I don’t want to allow my website’s videos to be saved.
However, using the video assistant function provided by the Samsung Internet App, users can easily download videos.
It seems to read the video tag of the html code.
I couldn’t find a way to prevent it myself, is there any way? I’ve sent an email to Samsung, but I haven’t received a reply yet, so I’m writing this. Help.

Try using MSE video type instead of HTML5.
