You are unlikely to be able to avoid paying down your regular mortgage payments (which will need to be made based on the required payment schedule). Instead, consider this in the context of what additional investing decisions you may make. Many people decide to only pay their required mortgage amounts every month, and if they have the financial means to do so, will decide to invest in the stock market [through their work pension plan or otherwise] instead of further reducing their debt.
The downside to doing this is that if you invest in assets with risk, then your overall return may be lower than if you had just made extra payments against your mortgage balance to reduce your ongoing interest. And you are unlikely to find a risk-free investment with a better return than your mortgage rate. So some people may prefer to pay off their mortgage early, rather than heavily invest [common advice is to always at least get your employer's pension match, if any, if you have the financial means to do so].
In most circumstances, your personal mortgage interest rate is likely the best 'risk free investment rate' that you can possibly earn. Conceptually, the reason your mortgage rate is typically higher than risk-free government borrowing, is that you as a borrower are a bigger risk to your bank than the government is, all else being equal.
Over time, the interest rate environment may change, and if your mortgage rate is fixed, then rising interest rates may cause government bonds to have higher payout rates than your mortgage rate. If your mortgage interest rate is lower than what you can earn through investing, then this means that at a bare minimum, you could likely benefit by making only the required payments, and using any surplus cash for investing in higher-rate fixed term investments. The opportunity to invest in higher-risk equities still exists, but with the same caveats as always.
