Same here with dell latitude 7490 (latest bios) displaylink 5.3.1 and evdi, 1.9.0\1.7.2 (tried both). kernel is 5.10.2, dock is hp universal docking station usb c.

The driver is loaded:
[entrop@entrop-dellpc Downloads]$ lsmod | grep evdi
evdi 69632 0
drm_kms_helper 217088 3 udl,evdi,i915
drm 557056 9 udl,drm_kms_helper,evdi,i915
i2c_core 81920 11 i2c_designware_platform,videodev,i2c_hid,i2c_desig nware_core,drm_kms_helper,i2c_algo_bit,evdi,i2c_sm bus,i2c_i801,i915,drm
the only GPU active is intel
[entrop@entrop-dellpc Downloads]$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x4a cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 7 associated providers: 0 name:Intel
