This cannot be controlled, it can only be set by default

In WeChat, the browser can ban it through API. I checked QQ's developer API, and there should be no such API.

or
This is suitable for opening in WeChat
<script>
function onBridgeReady(){
WeixinJSBridge.call('hideOptionMenu');
}
if (typeof WeixinJSBridge == "undefined"){

if( document.addEventListener ){
    document.addEventListener('WeixinJSBridgeReady', onBridgeReady, false);
}else if (document.attachEvent){
    document.attachEvent('WeixinJSBridgeReady', onBridgeReady); 
    document.attachEvent('onWeixinJSBridgeReady', onBridgeReady);
}

}else{

onBridgeReady();

}
</script>

Use QQ’s JS SDK to disable it,
mqq.ui.setTitleButtons({

                        left: {
                            title: "返回"
                         },
                        right: {
                            hidden: true
                        }
                        });
