How to use scikit-learn linear regression without using split?

I got 2 csv named train.csv and test.csv.

Both files have the same structure, and I want to use train.csv as train data and test.csv as test data.

The thing is, I can't find anywhere how to use scikit-learn linear regression without using split, every tutorial/documentation I find uses the function train_test_split(), but if I understand correctly it's used to split one file (let's sey data.csv) as both train and test data.

Is it even possible ? If no, what alternative can I use ?

Thanks.
