Disable scroll of ion-content

Ionic Framework ionic-v3
1

I need disable scroll of ion-content because im using ion-scroll on a custom component. Already tried set no-bounce and ion-fixed on ion-content. I also tried set this css:

.content .scroll-content {
        overflow: hidden;
}

but it doesnt works.

I just need disable the scroll of content and preserve the scroll of custom component.

Thanks in advance.
