The Samsung S10e, https://doc.e.foundation/devices/beyond0lte, is a quite different phone and the ROM will not be compatible. sorry 
The A10e, https://www.gsmarena.com/samsung_galaxy_a10e-9790.php, is also known as Samsung SM-A102Ux ā where x is the carrierās code and my quick research suggests these have a carrier locked bootloader, while SM-A102U1 is reported Unlocked, this might mean that no carrier is locked in, but maybe the bootloader is still locked, idk.
The presence of the locked bootloader probably explains very few useful hits in a search for āCustom ROM Samsung A10eā.
Samsung USA special models have unlockable bootloader.
When international models can be unlocked
But even with an international model, VoLTE (needed by USA carriers except one) donāt work on Samsung custom OS because it is a proprietary feature.
if you are in USA, forget Samsung devicesā¦
