I was able to resolve this issue by adding the following aura:html tag to the my component, NOT in the CSS style part of the bundle.
<aura:html tag="style">
.cuf-content {
padding: 0 0rem !important;
}
.slds-p-around--medium {
padding: 0rem !important;
}
.slds-modal__content{
overflow-y:hidden !important;
height:unset !important;
max-height:unset !important;
}
</aura:html>
