How to disable specific change_actions button in Django admin?

Question

I have a set of change_actions buttons on my Django Admin page:

A part of code for this particular InvoiceAdmin page:

from django_object_actions import DjangoObjectActions

class InvoiceAdmin(NGModelAdmin):
    def invoice_lines_link(self, request, obj):
        """ Set a button to the page of the Invoice's Invoice lines in the details view
        """
        return HttpResponseRedirect("{url}?invoice__pk={pk}".format(
            url=reverse("admin:backend_invoiceline_changelist"), pk=obj.pk
        ))
    invoice_lines_link.label = "Invoice Lines"

    def customer(self, request, obj):
        """ Set a button to the page of the InvoiceLine's Customer in the details view
        """
        return HttpResponseRedirect(reverse(
            "admin:backend_customer_change",
            args=[obj.customer.id]
        ))

    change_actions = ('customer', 'invoice_lines_link', 'test_link', 'pdf',)

I would like to have a button disabled, when other action in called. How can i refer to that button and disable it? It is not in a form and not marked as a action, so both get_form() and admin.site.disable_action wont work.

(I want to disable one of the grey buttons, that you can notice on the picture - it is not related to the form)
