It's worth taking a closer look at how Bitcoin mining works — this https://developer.bitcoin.org/devguide/mining.html Developer Guide on Mining is a great place to start.

In the Bitcoin protocol, the nonce is a critical part of the block header that miners change in order to produce a different hash output. Skipping nonces doesn't create more hashes — it just means you're choosing not to try certain values, which can reduce your chance of finding a valid hash.

If you're trying to optimize hash rate, it's better to look into overclocking, autotuning firmware (like AxeOS), or improving thermal performance — not skipping nonce ranges.
