Limiting Yocto Memory Usage

Hi,

I would like to know if there is a way to limit Bitbake's Memory usage to a
specific percentage of the available RAM. For example, can the Yocto build
be limited to use a maximum of 70% of RAM?

Could these three variables be used to achieve this?

 BB_PRESSURE_MAX_CPU
<https://docs.yoctoproject.org/dev/ref-manual/variables.html#term-BB_PRESSURE_MAX_CPU>
, BB_PRESSURE_MAX_IO
<https://docs.yoctoproject.org/dev/ref-manual/variables.html#term-BB_PRESSURE_MAX_IO>
 , BB_PRESSURE_MAX_MEMORY
<https://docs.yoctoproject.org/dev/ref-manual/variables.html#term-BB_PRESSURE_MAX_MEMORY>

I see the range for these variables is from 1 to 1000000, so I would like
to understand if there is a way to specify their values as a function of
the available RAM.
