No, it's still too risky to enable this feature in oem-5.6.
Maybe we'll enable this on 5.10 kernel.

Bug description:
[Impact]
PSR feature has been disabled by default because of below bug, "Dell XPS 13
(7390) Display Flickering - 19.10"
https://bugs.launchpad.net/bugs/1849947
But this feature is important to pass the new energy start standard,
so re-enable it and set default value to -1 "use per-chip default"
[Fix]
Revert the below commit to enable it again
ecc718f31c90 UBUNTU: SAUCE: drm/i915: Disable PSR by default on all
platforms
[Test]
Verified on one Dell platform which panel supports PSR
[Regression Potential]
High, we plan to verify all platforms that shipped with 5.6 OEM kernel to
make sure there is no flickering issue.
