Disable pull down dismissal of SFSafariViewController

Question

Is it possible to disable the pull down dismissal gesture of SFSafariViewController?

It seems like the SFSafariViewController runs in its own window, hence, setting isModalInPresentation or even setting the presentationControllerShouldDismiss(_:) doesn't seem to do anything.

The SFSafariViewController docs don't seem to specify anything here either.

MWE:

import SafariServices
import UIKit

class ViewController: UIViewController, UIAdaptivePresentationControllerDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()

        DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {
           let vc = SFSafariViewController(url: URL(string: "https://stackoverflow.com")!)
            vc.modalPresentationStyle = .pageSheet
            // `presentationControllerShouldDismiss` will be ignored, if isModalInPresentation is set to `true`
            // vc.isModalInPresentation = true
            vc.presentationController?.delegate = self

            self.present(vc, animated: true)
        }
    }

    func presentationControllerShouldDismiss(_ presentationController: UIPresentationController) -> Bool {
        return false
    }

    func presentationControllerDidDismiss(_ presentationController: UIPresentationController) {
        NSLog("Did dismiss")
    }
}
