You can reduce it
DECLARE @sql NVARCHAR(MAX) = ''
SELECT @sql = @sql + N'DBCC SHRINKFILE('+CAST(file_id AS NVARCHAR)+N', 0);'
FROM sys.database_files
WHERE type = 1
EXEC(@sql)
BUT it only works with a simple recovery model, instead you need to go back to the log and reduce it after
You cannot drop log files at all , even if your database is in read - only mode .
