Hi @Xander welcome to the /e/ forum.
I have no good news. The U in your model number is for USA. There is an /e/OS ROM for https://doc.e.foundation/devices/beyond0lte, Galaxy S10e, SoC Samsung Exynos 9820.
We see at the foot of the page
Models Supported
SM-G970F
Other models are not supported
The USA equivalent has a totally different Qualcomm processor and, sorry to say /e/ cannot be installed.
Some of the FAQs on Samsung + USA were covered in text and further links recently here: OEM unlock missing. Samsungs9+.
