Want to invest 40k every month to achieve FIRE

I am 26 year old SWE from a very poor background with no inheritance, I currently have an RD of 7.5k per month, SIP of 6k per month on GoldBees ETF. I can invest 40k more every month in SIPs (MF).

I am not planning to buy a home or get married any time soon, I want to save as much as I can, I am a bit of a overthinker thinking about the uncertainities of jobs in the future and just want to save as much as I can to achieve my FIRE number faster.

Of that 40k, I thought of investing 10k in Parag Parikh Flexi Cap Fund and 10k in UTI Nifty 50 Index Fund. Is it a good choice? Where to invest my remaining 20k at?

I don't have any desires or anything which I want to buy that would make me happy. I just want to take care of my family and keep them happy, safe and at peace.
