How to disable 'sort_by' in a One2many tree view

Question

What I want is simple, but I have no idea how to do it, I would be glad if anyone could help me So I have this One2many tree view :

For this model :

class StockInventoryDeGroupeLine(models.Model):
    
        _name = 'stock.inventory.degroupe.line'
        _order = 'sequence'
    
        stock_inventory_id = fields.Many2one(
            'stock.inventory',
            string='stock',
        )
        product_id = fields.Many2one(
            'product.product',
            string='Article',
        )
        quantity = fields.Float(
            string='Quantité',
        )
        display_type = fields.Selection([
            ('line_section', "Section"),
            ('line_emplacement', "Emplacement"),
            ('line_note', "Note"),],
            default=False,
            help="Technical field for UX purpose.")
        name = fields.Text(
            string='Description',
            required=False,
        )
        sequence = fields.Integer(
            string='Sequence',
            default=10,  
        )
        location_id = fields.Many2one(
            'stock.location',
            string='Emplacement',
        )
        prod_lot_id = fields.Many2one(
              'stock.production.lot', 
              'Lot/numéro de sérié',
               )
        product_tracking = fields.Selection(
            'Suivi', 
            related='product_id.tracking', 
            readonly=True)
    
        _sql_constraints = [('unique_seq','UNIQUE(sequence)',"La sequence doit être unique"),]
      
    
    
        @api.onchange('product_id', 'sequence')
        def onchange_product_id(self):
            for record in self:
                if record.display_type == False or record.display_type == 'line_emplacement' :
                    if record.sequence == 10 :
                        record.location_id = record.stock_inventory_id.location_id
                        return
                    else :
                        new_sequence = record.sequence -1
                        while new_sequence >= 10 :
                            for record2 in record.stock_inventory_id.degroupee_line_ids :
                                if record2.sequence == new_sequence :
                                    if record2.display_type != 'line_section':
                                        record.location_id = record2.location_id
                                        return
                            new_sequence -= 1
                
        @api.onchange('product_id','location_id','name')
        def onchange_sequence(self):
            for record in self :
                record.sequence += 1

When I'm in the editing mode, I want to disable sort by article, lot, emplacement... To make it simple, I want to have it sorted only by sequence

put your sequence field in one2many tree view as invisible..
