How to change the privacy settings on VK?

Question

Python

You need to close messages, that is, in the privacy settings, select "who can write me private messages" in the menu - no one.
The API does not have this, of course.
If everything is simple with other privacy settings -

url = 'https://m.vk.com/settings?act=privacy&privacy_edit=status_replies'

s = requests.session ()
#тут код для авторизации

data = s.get(url, headers=headers, proxies=proxies)
page = lxml.html.fromstring(data.content)
form = page.forms[0]
form.fields['val'] = 3

s.post('https://m.vk.com/' + form.action, headers=headers, proxies=proxies, data=form.form_values())

that is, simply through the mobile version.
But with HP, not everything is so simple. The LS also closes in this way, but after a few minutes it opens spontaneously. I don't know what it is, but I tested it on a lot of accounts.
The question is - is it possible to set the privacy settings for messages in VK using python without any selenium (I just couldn’t figure out how to use a proxy with authorization there, everything that is googled doesn’t work for some reason)
Save me, please

Answer 1

In short, since no one answered, I solved the problem like this.
How to use authorization proxy in Selenium with Firefox in Python? - here in this topic I read how to fasten a proxy with authorization to selenium, and more specifically to phantomJS.
Here through it I will change the privacy settings.
