U2415, dual, Latitude 7480, setup daisy chain

Chris, I need help. I have Dell Latitude 7480 business laptop and 2 U2415 monitors. I want to extend displays only only on 2 dell monitors with 1920x1200 resolution.

This is how setup the connections
Dell Latitude 7480 —> USB-C to Display port (in) —> Dell monitor 1 U2415 —> Display port (out) to mDP —> Dell monitor 2 U2415

I enabled DP1.2 in Dell monitor 1 and disabled DP1.2 in Dell monitor 2

Display is coming correctly in Dell monitor 1 with 1920x1200 resolution but not coming in Dell monitor 2. Can you please help? I do not want display in laptop just need them in Dell monitors with extended mode

Are you testing the Startech USB-C to DP cable?
Is the AC power adapter plugged into the Latitude 7480?
Is the Latitude 7480 lid closed?

Latitude 7480 USB Type-C/DP out port --> USB-C to DP cable --> #1 U2415 DP in port (DisplayPort 1.2 Enable)
#1 U2415 DP out port --> U2415 DP to mDP cable --> #2 U2415 mDP in port (DisplayPort 1.2 Disable)
