This is supported with target feature avx only.

Blends the f32 lanes according to the immediate mask.

Each bit 0 though 7 controls lane 0 through 7. Use 0 for the $a value and 1 for the $b value.

let a = m256::from_array([10.0, 20.0, 30.0, 40.0, 50.0, 60.0, 70.0, 80.0]);
let b =
  m256::from_array([100.0, 200.0, 300.0, 400.0, 500.0, 600.0, 700.0, 800.0]);
//
let c = blend_imm_m256!(a, b, 0b0011_0110).to_array();
assert_eq!(c, [10.0, 200.0, 300.0, 40.0, 500.0, 600.0, 70.0, 80.0]);
