Does activation energy depend on steric factors?

I thought that activation energy depends on steric factors. By Arrhenius equation it must depend on steric factors since $A$ depends on steric factors. $$k=A\cdot\mathrm e^{-\frac{E_\mathrm a}{RT}}$$ (for bimolecular reaction)

But my book says it doesn’t.

Does it depend on steric factors or not and why?
