Delete abstract from rticles::elsevier_article

I'd like to knit an article to a PDF document without an abstract. If I just leave out the abstract part in the YAML header, the Abstract headline is still produced in the document. Is there a way to drop this without changing the underlying function or document class?

I've tried such approaches as abstract: false or none which seem to work for some of the other YAML header arguments.

A reproducible YAML header which is a slightly modified version of the rticles package example:

---
title: Short Paper
author:
  - name: Alice Anonymous
    email: [email protected]
    affiliation: Some Institute of Technology
    footnote: 1
  - name: Bob Security
    email: [email protected]
    affiliation: Another University
  - name: Cat Memes
    email: [email protected]
    affiliation: Another University
    footnote: 2
  - name: Derek Zoolander
    email: [email protected]
    affiliation: Some Institute of Technology
    footnote: 2
address:
  - code: Some Institute of Technology
    address: Department, Street, City, State, Zip
  - code: Another University
    address: Department, Street, City, State, Zip
footnote:
  - code: 1
    text: "Corresponding Author"
  - code: 2
    text: "Equal contribution"

journal: "An awesome journal"
date: "`r Sys.Date()`"
bibliography: mybibfile.bib
#linenumbers: true
#numbersections: true
csl: elsevier-harvard.csl
output: rticles::elsevier_article
---

So the resulting document looks like this (the Abstract headline is what I'd like to get rid of):

Add

\renewenvironment{abstract}{}{}

to your header-includes. This will nullify the abstract environment.
