This bug was fixed in the package thermald - 1.9.1-1ubuntu0.2

thermald (1.9.1-1ubuntu0.2) focal; urgency=medium
* Performance workaround for Dell 7390 2-in-1 Ice Lake (LP: #1874933)
- 5.4 kernel added support for "Processor thermal device" for Ice Lake
via the PPCC power tables. The power table specified for Dell 7390
2-in-1 specifies this as 9W so thermald will limit it to this.
This is a workaround that will ignore power limits less than the
power up power limit to workaround this throttling. Requires a
couple of prerequisite patches to apply and final 2 patches for
the fix.
- eeadf7d2efe Restore to min state on deactivation without
depending on hardware state
- 9a6dc27879a Clean up the code and documentation
- f7db4342933 Avoid polling power in non PPCC case
- c3461690eaf Ignore invalid PPCC max power limit
