kindly we have 2 2960x switch stacked and we have 1 fortigate 60D mode hardware switch and this fortigate don't support Link aggregation and we need to connect with fortigate by 2 uplink 1 from each edge switch and when we do this we create a loop because this model don't support STP and work as a hub . what we can to do to connect with this forte be 2 links and dont create loop and we need only one port active and another port block by STP

If the Fortigate does not support layer-2 and you have to have 2 links, you maybe force to use 2 layer-3 links.

Why not try and use Cisco flex link? I have done this with a fortigate FG-90d.
Something like this...
interface GigabitEthernet1/0/24
description Firewall-Primary
switchport mode trunk
switchport backup interface Gi2/0/24
