Hello,

Please add this code to the Theme Settings > Custom CSS > Global:

.page-title:before {
	content: "";
	position: absolute;
	top: 0;
	left: 0;
	right: 0;
	bottom: 0;
	background-color: #000;
	opacity: 0.5;
}

You can change background-color: #000; and opacity: 0.5; as per your needs.

Best Regards
