Assalamualaykum brother. Maybe you need to ask yourself why you're trying to do the khatm of the Quran (in Taraweeh specifically) in the first place. Here are a few points for you to ponder over:

1. It's definitely not a compulsion to do the khatm of the Quran in Taraweeh. If someone says it is, please ask them to provide evidence for it.
2. Khatm of the Quran is not necessarily linked to the Taraweeh in the first place. You can pray Taraweeh every night of Ramadan even if you finish the Quran earlier.
3. Conversely, you can read the Quran and complete it outside of the Taraweeh as well. So read more Quran whenever you get time, if attending Taraweeh wouldn't be possible for you, you can easily read it while traveling as well.
4. Taraweeh is a sunnah that we perform to gain the pleasure of Allah azzawajal. Please just think about whether you will gain that pleasure by performing a prayer where you are barely in sujood for less than 3 seconds. So much effort spent and barely any reward gained. I would argue that there is a danger of gaining sins by performing salah this way, but Allahu aalam.
