I was able to go over it by adding a className with border: none
like this:

<Iframe url="some url"
        width="100%"
        height="10780px"
        id="myId"
        loading="Loading...."
        className="myClassname"
        display="initial"
        position="relative"
        allowFullScreen
        className="myClassname"/>

and then in my css

.myClassname{
border:none
}
