I see that you are trying to load the rshim driver on the BlueField system,
which is wrong.

- rshim user-space driver is used on the external host that hosts the BlueField
card.
- on the BlueField, we have a module named mlxbf_tmfifo that creates the
corresponding interface that links to the rshim interface on the external host.

> [root@mellanox-bluefield-01 p]# uname -r
> 4.18.0-188.2.el8.bz1655714.v1.aarch64

This kernel build has the mlxbf_tmfifo driver.
