Hi @terminator99,
Thank you for your question.
You can achieve it by adding the following CSS code in the Custom CSS code option of your theme on the below path.
Admin Area -> Appearance -> Theme Settings -> Custom Code -> CSS Code
.post-meta-content span.post-auhor-date > span .post-author,
.post-meta-content span.post-auhor-date {
font-size:0 !important;
}
