Dynamically add *ngIf in a directive

how can I dynamically add an *ngIf to an element that's decorated with an attribute directive?

For a simple experiment, I tried this:

@Directive({
    selector: '[lhUserHasRights]'
})
export class UserHasRightsDirective implements OnInit, OnDestroy {
    constructor(private el: ElementRef) {
    }

    ngOnInit(): void {
        this.el.nativeElement.setAttribute("*ngIf", "false");
    }

    ...

, but it didn't work. The browser showed me an error "ERROR DOMException: Failed to execute 'setAttribute' on 'Element': 'ngIf' is not a valid attribute name."
