The HP under consideration comes with the i7-1165G7 CPU which features a configurable TDP range of 12W to 28W. In theory, therefore, this CPU is available in 16 different versions.
Normally, the computer manufacturer sets the default TDP point, and consumers are not supposed to change this value. In enterprise CPUs the value can be changed by IT staff either via the BIOS or by using specialized software. Some consumer-grade CPUs may be changed by consumers, but only if the computer manufacturer has made that option available. HP typically do not allow consumers to change TDP values.
Moreover, it is practically impossible to ascertain the "manufacturer TDP value" for your particular PC prior to purchase. Once you've bought the PC, you can use HWInfo and similar hardware apps to view TDP details.
Here is an article from November 2020 comparing 2 ASUS PCs - both with the i7-1165G7 CPU, one with 15W TDP and the other with 28W TDP:
Today what we have here are two laptops from ASUS. They're both running the latest 11th Gen Intel Core i7-1165G7 chips, but their maximum operating wattage is completely different.
