This is not true. On a drag car this is the preferred location for the fuel cell.
It is much safer under hood.
As long as it is mounted and plumbed correctly, it is fine and will pass track tech.
Be sure that the length of flexible hose that runs from the firewall to the engine
for the nitrous system is good braided steel line.
Small 1 gallon to 3 gallon upright style fuel cells that mount underhood are readily available.
Thats what they are for.

If you look, at the track you will find many drag cars with the fuel cell and fuel system all underhood
whether a nitrous car or not. Ther are many advantages to having the fuel cell and pump mounted under hood,
including safety. Including the fact that the volume of fuel onboard is much less.
Having the fuel cell mounted close to the engine negates the need for high fuel pressure.
5 to 7psi for the carb is just fine and 5 to 8 psi is fine for the nitrous system with a adjustable regulator.
The nitrous fuel system response and pressure regulation is much more consistant.
