Static route you try to configure will be removed from virtual router only if interface physically goes down.
If you would have static IPs from ISP you could set up path monitoring inside the static route.
What you are trying to accomplish is as good as leaving "automatically install the default route from the isp" in place and setting route metric on one DHCP interface to 10 and 200 on other.
You can't configure path monitoring if your interface don't have IP.
Theoretically you could wait for DHCP to pick up gateway IP and then set up PBF with next hop to that gateway IP.
And then second PBF under first one towards secondary ISP.
If your ISP don't change subnet then gateway should be more or less the same all the time.
As PBF is processed before virtual router if there is matching PBF then virtual router is bypassed.
