How to Save tax in India if you have low spending and salary above 15LPA

I have recently started to look at my tax bill as this is the first time for me after 2 year of working in tech now able to cross 10 LPA and now getting paid around 13~16 LPA in cash.

The tax burden looks massive with new tax regime upwards of 2 Lac need to be paid and for old tax for a person with no student loan left , no plan to get a home anytime soon and also live in quite modest rented and home place so rent allowance is less then 2 LPA .

Also have good way to buy equity may it be US or indian equity like most savings goes their and looking at past 4 years other investments don’t matter that much.

I personally currently work at company that work in consultancy so can’t do much of other ways like NGO and Political funding to get around.

I guess my income is not that uncommon so how other people save tax.

Note I can’t give rent to my parents as either they are in higher or similar tax bracket as me.
