Hi i want to overwrite this methode

class AccountMove(models.Model):
    _inherit = 'account.move'

    def _post(self, soft=True):
        # OVERRIDE to check the invoice lines taxes.
        for invoice in self.filtered(lambda move: move.is_invoice()):
            for line in invoice.invoice_line_ids:
                account_tax = line.account_id.tax_ids.ids
                if account_tax and invoice.company_id.account_fiscal_country_id.code == 'DE':
                    account_name = line.account_id.name
                    for tax in line.tax_ids:
                        if tax.id not in account_tax:
                            raise UserError(_('Account %s does not authorize to have tax %s specified on the line. \
                                Change the tax used in this invoice or remove all taxes from the account') % (account_name, tax.name))
        return super()._post(soft)

the problem is can recreate the methode in an own module but the code is stil executed. how can i overwrite this methode exactly or prevent this method from beein called
