The phrase "a modest attenuation of" is correct and usable in written English.
It can be used in contexts where you want to describe a slight reduction or weakening of something, such as an effect, signal, or intensity.
Example: "The study revealed a modest attenuation of the drug's efficacy over time."
Alternatives: "a slight reduction in" or "a minor decrease in".

Bilateral lesions of the neurokinin1 receptor-expressing neurons in the RTN region by injection of saporin conjugated to a substance P analogue have produced variable results, ranging from a modest attenuation of the chemoreflex in an earlier study (Nattie and Li, 2002) to a substantial decrease in recent work (Takakura et al., 2014).
