If you try that approach it would be global change I believe since it will for all catalog items.

1)  If you want this for all catalog items then you can disable those 2 drop down choices of 9 and 10 for sc_cart_item table

2) if you want for specific catalog item then you can have onSubmit catalog client script to check for quantity

Ensure: Isolate script is set to false; this field is not on form but from list you can set it to false; by default it is true

Sample Script below; it worked for me in native and portal both

Note: this includes using DOM manipulation

function onSubmit() {
	//Type appropriate comment here, and begin script below

	if(window == null){
		var z = this.document.getElementsByClassName("select2-chosen");
		if(z[1].innerHTML > 8 ){
			alert('Please select value less than 8');
			return false;
		}
	}
	else{
		var quantity = $j('#quantity').val();
		if(quantity > 8){
			alert('Please select value less than 8');
			return false;
		}
	}
}
