two buffers in series next to eachother

is it fine to have 2 buffers back to back early in the chain?

i have a compressor > a deco V1 > a poly tune 3 mini > the rest of my board which is 8 more pedals without buffers.

the deco and the tuner both have options for buffers to be switched on or off. does having both on have a negative effect? or is it just redundant and that’s it.

just curious about this.

thanks
