Selenium grid, firefox specific functionality

I have configured a selenium grid instance in kubernets. Which has a deployment that looks somewhat like this:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: selenium-standalone-worker
  namespace: default
  labels:
    app: selenium-standalone-worker
spec:
  replicas: 1
  selector:
    matchLabels:
      app: selenium-standalone-worker
  template:
    metadata:
      labels:
        app: selenium-standalone-worker
    spec:
      volumes:
        - name: shmem
          emptyDir:
            medium: Memory
            # sizeLimit: 2Gi
      containers:
        - name: selenium-standalone-worker-container
          image: selenium/standalone-firefox:144.0-20251101
          imagePullPolicy: Always
          ports:
            - containerPort: 4444
          resources:
            requests:
              cpu: "500m"
              memory: "512Mi"
            limits:
              cpu: "1"
              memory: "1Gi"
          volumeMounts:
            - name: shmem
              mountPath: /dev/shm
          env:
            - name: SE_START_VNC
              value: "false"
          readinessProbe:
            exec:
              command:
                - sh
                - -c
                - 'curl -s http://localhost:4444/wd/hub/status | grep ''"ready": true'''
            initialDelaySeconds: 5
            periodSeconds: 10
          livenessProbe:
            httpGet:
              path: /wd/hub/status
              port: 4444
            initialDelaySeconds: 15

I would really like to use firefox specific functionality, when my remote webdriver connects to the grid firefox instance.

More specifically I would like to use the driver.get_full_page_screenshot_as_png() firefox functionality.

I suppose I would need to respectively configure the node and my client remote webdriver implementation, but to be honest I'm pretty unsure how to go about this.
