X-Content-Type-Options Header Missing

I have run Zap scanning tool on my Grafana Project. we are using grafana 6.7.3 version.
Zap has reported X-Content-Type-Options Header Missing alert. Below is detail of Alert -

Low (Medium) X-Content-Type-Options Header Missing
Description The Anti-MIME-Sniffing header X-Content-Type-Options was not set to ‘nosniff’. This allows older versions of Internet Explorer and Chrome to perform MIME-sniffing on the response body, potentially causing the response body to be interpreted and displayed as a content type other than the declared content type. Current (early 2014) and legacy versions of Firefox will use the declared content type (if one is set), rather than performing MIME-sniffing.
