Yes, the hub is identical
Same 5x120 PCD and same 64.1 mm centre bore: wheels from BYD Seal bolt on and centre on Nio ES8 without rings. You still need to check the offset and tyres, detailed below.
≈: width estimated from the original tyre size.
Wheel by wheel: offset and tyres
Each original wheel from BYD Seal is compared with the one from Nio ES8 of the same diameter: how much closer the wheel gets to the shock absorber or how far it sticks out of the wheel arch, and whether the tyre keeps the same overall diameter.

≈7.5Jx19 ET41 · 245/45R19 — Fits like the original
Compared with the original ≈8Jx19 ET43 on Nio ES8: shock absorber side −8.3 mm, wheel arch side −4.3 mm, tyre diameter −7.9 % : fit it with the original tyre size of Nio ES8 (255/55R19), not that of BYD Seal.

Before fitting the wheels
An identical hub is not enough: offset, width and diameter change the position of the wheel, and larger calipers can touch a smaller wheel. Original wheels often use bolts or nuts with a specific seat: keep the fixings intended for the wheel, with the thread of Nio ES8 (- 14x1.50), tightened to the torque shown on its vehicle page. Finally, check that the size is among the approved fitments for your vehicle. This comparison is for guidance only: have the fitting approved by a professional.
