If 2019 has the equipment as current, it s a 2x with a derailleur rd rx810 which is maxed with a 34 cassette already on.
so you could try a 11-36 that would help a little (not much) or swap the chain ring; 48-31 to move to 42-28.
if you’re thinking bigger budget, move to 1x11 set up: rear derailleur, 11-46 cassette, single 38 chainring Or a 36 if you want to ease further.
and if you have a rather large budget, get raid of the groupset and fit grx di2 shifter with a deore xt di2 groupset
