I want to hide the two validate buttons of the stock picking based on the following:
- I created the fields check_docs which is a boolean field that is enabled when check_docs_id (invisible) is true when finding 3 types of operations that I previously defined. check_docs is a reminder not to forget certain documentation. This works fine.
What does not work is that when one of these 3 types of operations is chosen, if check_docs is false, no "Validate" button for picking should be enabled. When check_docs is true, it is only possible to enable the "validate" buttons. But that this rule does not interfere with the validation of the picking of other types of operations other than these 3.

Python----

class CustomStockPicking(models.Model):
    _inherit = 'stock.picking'

    check_docs_id = fields.Boolean(default=False, compute='_check_docs')
    check_docs = fields.Boolean('Documentación', default=False)
    check_validate = fields.Boolean(compute='_check_validate', default=False)

    @api.depends('picking_type_id')
    def _check_docs(self):
        for picking in self:
            if picking.picking_type_id.id == 25 or picking.picking_type_id.id == 26 or picking.picking_type_id.id == 27:
                picking.check_docs_id = True
            else:
                picking.check_docs_id = False

    @api.depends('show_validate')
    def _check_validate(self):
        for picking in self:
            if picking.check_docs_id:
                if picking.check_docs and picking.show_validate:
                    picking.check_validate = True
                elif picking.check_docs and not picking.show_validate:
                    picking.check_validate = False
                elif not picking.check_docs and picking.show_validate:
                    picking.check_validate = True
                else:
                    picking.check_validate = False
            else:
                picking.check_validate = False
