Yes thats it Elvin. I think you have answered the question. Replace the SVG’s with an Image?
It’s not recommended to use non-vector image files as they don’t translate well on resize but if you must still do it, check the button block’s Icon tab.
You should see a text field containing an SVG tag. <svg .........>

You can replace that with an <img>
tag. You can manually add attributes as well.
Example:
<img src="path/to/your/image/filename.png" height="20" width="20" alt="your manual alt text" />
