From what I've read, there's not a huge profit margin on bikes themselves... more so on accessories. So you could certainly ask, but I don't think it's reasonable to expect them to say yes. Especially since you're looking at a 2020 model and not a 2019 or older. Typically they'll offer 10% or 20% off of accessories purchased with the bike, and/or a discount on future service (other than the customary free tune-up after the first few months of riding).
