SD-WAN and BGP

Hi fortiexpers,
I'm having and issue. On one hand I have a BGP peering two ISP. That works fine, and I'm routing traffic thru there. Also I have two ISP only for lan users. I have configured an SDWAN. The problem is the routing table. I have created an static route with same weight of the bgp, but when I do that BGP routes are not more default. I change the weight of the static route, increasing it, BGP becomes default again, but lan users can not navigate. I can't create a policy route, because is not avaible the option to use sdwan.
This is my routing table database
FGT02COMARB # get router info routing-table database
 
Routing table for VRF=0
Codes: K - kernel, C - connected, S - static, R - RIP, B - BGP

       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area

    did you try same weight, but different priority? that is how you usually get multiple default routes in your routing table.
