You can pass use_columns with the calamine engine:
>>> pl.read_excel("random.xlsx", engine="calamine", read_options={"use_columns": "B:D"})
# shape: (3, 3)
# ┌──────────┬──────────┬──────────┐
# │ column_1 ┆ column_2 ┆ column_3 │
# │ --- ┆ --- ┆ --- │
# │ f64 ┆ f64 ┆ f64 │
# ╞══════════╪══════════╪══════════╡
# │ 0.900042 ┆ 0.034829 ┆ 0.110054 │

Yup, we should expose this as a top-level option; in the meantime you can use the engine-specific read_options parameter as suggested by @cmdlineluser (and the advice the use the "calamine" engine is also on-point as it's extremely fast, and will eventually become our new default ;)
