How to define block wrapping in Bootstrap 4 (flex)?

Question

css

I'm making a photo gallery using the bootstrap 4 grid (flexbox). Blocks go one after another. The first block takes up half the width, all other blocks take up 1/4. Tell me, is it possible to perform the necessary transfer of blocks (4 and 5) without creating additional wrappers (See the picture)?
