It's not clear whether you want just power, or power and data. Many USB-C cables that support 100W only support USB 2.0 data which should exclude DP Alt Mode. You can also find USB cables for "charging only", you'd have to look for a USB-C product that can deliver enough power to a MacBook Pro. If you have an Apple Silicon Mac then 65W is enough for any MBP unless you need to fast charge or have a Pro or Max chip and run sustained high loads.
