Evaluate environment variable read from file in batch

I read in the file repos.txt by the script:

@echo off

for /F %%s in (%~dp0repos.txt) do (
    echo %%s
)

The file repos.txt contains the lines:

%UserProfile%\Documents\Repository\A
%UserProfile%\Documents\Repository\B

The echo command gives me the directories without evaluating the environment variable %UserProfile%. This is a problem when I would like to use it with git.

How can I evaluate the environment variable?

I tried setlocal like done here and the surrounding with exclamation marks. Unfortunately, nothing gives the correct output.

Command call can be used to expand environment variables on assigning to an environment variable as this code demonstrates:

@echo off
setlocal EnableDelayedExpansion
for /F "usebackq eol=| delims=" %%s in ("%~dp0repos.txt") do (
    set "RepositoryPath=%%s"
    echo Not expanded: !RepositoryPath!
    call set "RepositoryPath=%%s"
    echo And expanded: !RepositoryPath!
)
endlocal
