From my experience, you can’t add new fields after super().init(). and fields doesn’t exist before the _init. So the work around to always include the optional fields and then remove after init if they are not needed.

class JoinForm(forms.ModelForm):
    captcha = NoReCaptchaField(gtag_attrs={'data-theme': 'light'})

    class Meta:
        model = InterestedUser
        fields = ('email', 'name', 'subject', 'via', 'content',)

    def __init__(self, needs_captcha, *args, **kwargs):
        super().__init__(*args, **kwargs)

        if not needs_captcha:
            del self.fields['captcha']
