Also, before you start, see if the ceiling is sloping the same way, and if
doors, at right angles to the beam, have the same slope to the jamb top and
if doors have been cut to fit that angle. They will have to be fixed if
lowering the beam makes them stick. In other words check out everything
before you start and regularly as you adjust it. If you have lead-sealed
cast iron soil-pipe drains, some horizontal sections may need their supports
adjusted as you work, some joints may loosen and slopes may change requiring
remedial work.

The previous owner of the house I own replaced the main beam. The beam is

the main level of the house slopes upwards towards where the beam, by as

anything?

"without hurting anything?" Probably not, but if you are patient and
go really slow backing the jacks down it might be minimal. By slowly I
mean months or years. If they are screw jacks & you give each one a 1/4
turn once a month it would eventually hit the level you want, maybe
without putting big cracks in the walls.
